IDLE AIR VALVE
A cover is in place over t
he idle air bleed valve. Also , the access holes to the
idle mixture needles are s ealed with hardened plugs. This is done to seal the
factory settings, during original equipment production. These items are NOT to
be removed unless required for cleaning, part replacement, improper dwell
readings or if the System Performance Check indicates the carburetor is the
cause of the trouble.
ROCHESTER E4ME AND E4MC
1. With engine OFF, cover the internal bowl vents and inlet to bleed valve
and the carburetor air intakes with maski ng tape. This is done to prevent
metal chips from entering.
2. Carefully drill rivet head of idle air bleed cover, with 0.110 in. (2.8mm) drill bit.
3. Remove rivet head and all pieces of rivet.
4. Lift cover off air bleed valve and bl ow out any metal shavings, or use a
magnet to remove excess metal.
CAUTION - Always wear eye protection when using compressed air.
5. Remove masking tape.
6. Start engine and allow it to reac h normal operating temperature.
7. Disconnect the vacuum hose from t he canister purge valve and plug it.
8. While idling in D for automatic transmission or N for manual
transmission, slowly turn the valve c ounterclockwise or clockwise, until
the dwell reading varies within the 25-35 degree range, attempting to be
as close to 30 degrees as possible.
Perform this step carefully. The air bleed valve is very sensitive and should be
turned in
1/8 turn increments only.
9. If the dwell reading d oes not vary and is not within the 25-35 degree
range, it will be necessary to remove the plugs and to adjust the idle
mixture needles.

INJECTOR REPLACEMENT
Use care in removing injectors to prev
ent damage to the electrical connector
pins on top of the injector, the fuel injector fuel filter and nozzle. The fuel injector
is serviced as a complete assembly on ly and should never be immersed in any
type of cleaner.
SINGLE INJECTOR UNITS 1. Relieve the fuel system pressure.
2. Remove the air cleaner.
3. Detach the injector connector by squeezing the two tabs together and
pulling straight up.
4. Remove the screws securing the fuel meter cover. Note the location of
any short screws for correct placement during reassembly.
CAUTION - DO NOT remove the four screws se curing the pressure regulator to
the fuel meter cover. The fuel pressure regulator includes a large spring under
heavy tension which could cause personal injury if released.
5. With the old fuel meter gasket in place to prevent damage to the casting,
use a prytool and fulcrum to pry the inje ctor carefully until it is free from
the fuel meter body.
6. Remove the injector.
7. Remove the large O-ring and steel back-up washer at the top of the
injector cavity in the fuel meter body.
8. Remove the small O-ring located at the bottom of the injector cavity.
To Install: 9. Lubricate the new, small O-ring with automatic transmission fluid; then,
push the new O-ring on the nozzle end of the injector up against the
injector fuel filter.
10. Install the steel backup washer in the recess of the fuel meter body.
Lubricate the new large O-ring with automatic transmission fluid, then
install the O-ring directly above t he backup washer, pressing the O-ring
down into the cavity recess. The O-ri ng is properly installed when it is
flush with the casting surface.
WARNING - Do not attempt to reverse this procedure and install the backup
washer and O-ring after the injector is located in the cavity. To do so will
prevent proper seating of the O-ring in th e cavity recess which could result in a
fuel leak and possible fire.
11. Install the injector by using a pushing/twisting mo tion to center the nozzle
O-ring in the bottom of the injector cavity and aligning the raised lug on
the injector base with the notch cast into the fuel meter body. Push down
on the injector making sure it is fully seated in the cavity. Injector
installation is correct when the lug is seated in the notch and the
electrical terminals are parallel to the throttle shaft.

MINIMUM IDLE AND THROTTL
E VALVE SYNCHRONIZING
The throttle position of each throttle body must be balanced so that the throttle
plates are synchronized and open si multaneously. These adjustment
procedures must be followed AFTER performing the "Preliminary Adjustments".
1. Remove the air cleaner and plug the vacuum port on the rear TBI unit for
the thermostatic air cleaner.
2. Remove the tamper resistant pl ugs covering both unit throttle stop
screws, if necessary.
3. Block the drive wheels and apply the parking brake.
4. Connect a tachometer to measure rpm.
5. Start the engine and allo w the engine rpm to stabilize at normal operating
temperature.
6. Have a helper apply the brakes and place the transmission in DRIVE.
7. Plug the idle air pass ages of each throttle body with plugs (J-33047 or
equivalent). Make sure the plugs are seated fully in the passage so that
no air leaks exist. The engine rpm should decrease below curb idle
speed. If the engine rpm does not decreas e, check for a vacuum leak.
8. Remove the cap from the ported tube on the rear TBI unit and connect a
vacuum gauge or water manometer.
9. Adjust the rear unit throttle stop screw to obtain approximately
1/2 in. Hg
as read on the vacuum gauge, or 6 in. H
2O as read on the manometer. If
not able to adjust to this level, check that the front unit throttle stop is not
limiting throttle travel.
10. Remove the vacuum gauge or manometer from t he rear unit and install
the cap on the port ed vacuum tube.
11. Remove the cap from the ported va cuum tube on the front TBI unit and
install the gauge or manomet er as before. If the reading is not the same
as the rear unit, proceed as follows: a. Locate the throttle synchronizing screw and collar on the front TBI
unit. The screw may be welded to discourage tampering with this
adjustment. Break the weld, if ne cessary, and install a new screw
with a thread seali ng compound applied.
b. Adjust the screw to obtain approximately
1/2 in. Hg as read on the
vacuum gauge, or 6 in. H
2O on the manometer.
12. Remove the gauge or manometer fr om the ported tube and reinstall the
cap.
13. Adjust the rear throttle stop screw to obtain 475 rpm, with the
transmission in D and the parking brake applied. On manual
transmission models, leave the gear selector in N.
14. Turn the ignition OFF and pl ace automatic transmission in N.
15. Remove idle air passage plugs.
16. Start the engine. It may run at a high rpm but the engine speed should
decrease when the idle air control va lves close the air passages. Stop
the engine when the rpm decreases.
17. The throttle position sensor (TPS) voltage should be checked and adjusted, if necessary.
18. Connect the vacuum line to the TBI unit and install the air cleaner.
19. Reset the idle speed control motors by driving the vehicle to 45 mph.

MAINTENANCE OR REPAIR?
Maintenance includes routine inspecti
ons, adjustments, and replacement of
parts which show signs of normal wear . Maintenance compensates for wear or
deterioration. Repair implies that someth ing has broken or is not working. A
need for a repair is often caused by lack of maintenance. for example: draining
and refilling automatic transmission fl uid is maintenance recommended at
specific intervals. Failure to do this can shorten the life of the
transmission/transaxle, requiring very expen sive repairs. While no maintenance
program can prevent items from eventually breaking or wearing out, a general
rule is true: MAINTENANCE IS CHEAPER THAN REPAIR.
Two basic mechanic's rules should be mentioned here. First, whenever the left
side of the vehicle or engine is refe rred to, it means the driver's side.
Conversely, the right side of the vehi cle means the passenger's side. Second,
screws and bolts are removed by turn ing counterclockwise, and tightened by
turning clockwise unless specifically noted.
Safety is always the most important rule. Constantly be aware of the dangers
involved in working on an automobile and take the proper precautions. Please
refer to the information in this se ction regarding SERVICING YOUR VEHICLE
SAFELY and the SAFETY NOTICE on the acknowledgment page.
AVOIDING THE MOST COMMON MISTAKES
Pay attention to the instructions prov ided. There are 3 common mistakes in
mechanical work:
1. Incorrect order of assembly, di sassembly or adjustment. When taking
something apart or putting it toget her, performing steps in the wrong
order usually just costs you ex tra time; however, it CAN break
something. Read the entire proc edure before beginning. Perform
everything in the order in which the instructions say you should, even if
you can't see a reason for it. When you' re taking apart something that is
very intricate, you might want to draw a picture of how it looks when
assembled in order to make sure you get everything back in its proper
position. When making adjustments, per form them in the proper order.
One adjustment possibly will affect another.
2. Overtorquing (or undertorquing). While it is more common for overtorquing to cause damage, undertorquing may allow a fastener to
vibrate loose causing serious dam age. Especially when dealing with
aluminum parts, pay attention to tor que specifications and utilize a torque
wrench in assembly. If a torque figure is not available, remember that if
you are using the right tool to perfo rm the job, you will probably not have
to strain yourself to get a fast ener tight enough. The pitch of most
threads is so slight that the te nsion you put on the wrench will be
multiplied many times in actual fo rce on what you are tightening.
There are many commercial products avai lable for ensuring that fasteners won't
come loose, even if they are not torqued just right (a very common brand is

10. Refill the engine with the correct amount
of fresh oil. Please refer to the
Capacities chart at the end of this section.
11. Check the oil level on the dipstick. It is normal for the level to be a bit
above the full mark. Start the engine and allow it to idle for a few
minutes.
CAUTION - Do not run the engi ne above idle speed until it has built up oil
pressure, as indicated w hen the oil light goes out
12. Shut off the engine and allow the oil to flow back to the crankcase for a
minute, then recheck the oil level. C heck around the filter and drain plug
for any leaks, and correct as necessary.
MANUAL TRANSMISSIONS
FLUID RECOMMENDATIONS
• 1982-85 4-speed manual transmissi ons - SAE 80W/90 GL-5 gear
lubricant
• 1986-87 4-speed manual transmission - Dexron®®II automatic
transmission fluid
• 1982-84 5-speed manual transmissions - use SAE 80W/90 GL-5 gear
lubricant (SAE 80W GL-5 in Canada)
• 1985-92 5-speed manual transmissi ons - Dexron®II automatic
transmission fluid
LEVEL CHECK
The oil in the manual tr ansmission should be check ed every 12 months or
15,000 miles.
1. Raise the car and support on jackstands as close to level as possible. \
2. Remove the filler plug from the side of the transmission housing.
3. If lubricant begins to trickle out of the hole, there is enough and you need
not go any further. Otherwise, carefully insert your finger (watch out for
sharp threads) and check to see if the oil is up to the edge of the hol\
e.
4. If not, add oil through the hole until the level is at the edge of the hole.
Most lubricants come in a plasti c squeeze bottle with a nozzle; making
additions simple.
5. Install and tighten the filler plug.
DRAIN AND REFILL
The fluid in the manual transmission do es not require changing. If you do
choose to change the transmission fluid, the fluid can be drained out through
the lower drain plug hole on the side of the transmission. Fill the transmission
with the recommended lubricant to the bottom of the filler plug hole and install
the filler plug.

AUTOMATIC TRANSMISSION
FLUID RECOMMENDATIONS
Use only Dexron®II Automati
c Transmission Fluid.
LEVEL CHECK

Fig. 1: Read automatic transmission flui d level on dipstick and add, as required
Check the automatic transmission fluid le vel at each oil change. Driving with too
much or too little transmission fluid ca n damage the transmission. The dipstick
can be found in the rear of the engine compartment. The fluid level should be
checked only when the transmission is at normal operating temperature. If your
Camaro has been driven at highway speeds fo r a long time, in city traffic in hot
weather, or pulling a trailer, wait for about 30 minutes for the fluid to cool down
so a correct reading can be read.
1. Park the car on a level surface, with the parking brake on. Start the
engine and let it idle for about 15 minutes. Move the transmission
through all the gears and then back to P.
2. Remove the dipstick and carefully touch the wet end of the dipstick to see if the fluid is cool, warm, or ho t. Wipe it clean and then reinsert it
firmly. Be sure that it has been pushed all the way in. Remove the
dipstick again and check the fluid leve l while holding it horizontally.
a. If fluid is cool (room temper ature), the level should be about
1/8-3/8
in. (3-10mm) below the ADD mark.

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 784
b. If fluid is warm, the le
vel should be close to the ADD mark, either
above or below.
c. If fluid is too hot to touc h, the level should be at the FULL mark.
3. If the fluid level is low, add Dexr on®II automatic transmission fluid (ATF)
through the dipstick tube. This is eas ily done with the aid of a funnel.
Check the level often as you are f illing the transmission. Be extremely
careful not to overfill it. Overfilling will cause slippage, seal damage and
overheating. Approximately 1 pint (0.473L) of ATF will raise the fluid level
from one notch/line to the other.
If the fluid on the dipstick appears discolored (brown or black), or smells burnt,
serious transmission troubles, probably due to overheating, should be
suspected. The transmission should be inspected by a qualified technician to
locate the cause of the burnt fluid.
DRAIN AND REFILL
Please refer to the "PAN AND FILTER SERVICE" procedure listed in this
section.

The automatic transmission fluid and fi
lter should be changed every 15,000
miles (24,000km) if your Camaro is driven in heavy city traffic in hot weather, in
hilly or mountainous terrain, frequent trailer pulling, or uses such as found in
taxi, police car or delivery service. If your Camaro is driven under other than
listed above conditions, change the fl uid and filter every 30,000 miles
(48,300km).
1. Raise and support the car on jackst ands. Place an oil catch pan under
the transmission.
2. Remove the oil pan bolts fr om the front and sides only.
3. Loosen rear oil pan bolts approximately 4 turns.
WARNING - Do not damage the transmission case or oil pan sealing surfaces.
4. Lightly tap the oil pan with a rubber mallet or gently pry it downward to
allow fluid to drain.
5. Remove the remaining oil pan bolt s, then remove the oil pan and pan
gasket.
6. Remove the filter and seal.
7. Clean the transmission case and oi l pan gasket surfaces with suitable
solvent and air dry. Make sure to re move all traces of the old gasket.
To install: 8. Coat the seal with a sm all amount of Transjel®.
9. Install the new s eal onto the filter.
10. Install the new filter into the case.
11. Install the oil pan and new gasket.
On 1991 and later vehicles, inspect t he oil pan screws and washer assemblies.
The screws must not be used if the coni cal washer is reversed. Failure to
replace the screw and washer assembly may result in improper fastening of
system components.
12. Install the oil pan bolts and tighten them to 12 ft. lbs. (16 Nm).
13. Lower the car.
14. Fill the transmission to proper level with Dexron®II fluid.
15. Check cold fluid level reading fo r initial fill. Do not overfill the
transmission.
