Restart and idle the engine with no-load conditions
for one minute, then check the idle speed.
NOTE: (Canada) Pullthe parking brake lever up.
Start the engine, then check that the headlights are off.

NOTE: 81881, Bl8Cl engines - It the idle speed
increases to *1rpm, this means the EVAP system ispurging the canister. To stop the purging termporarily.
raise the engine speed above 1,000 rpm with the

. When setting the idle speed, checkthe following items:- The MIL has not been reported on.- lgnition timing
Spark plugs- Air cleaner- PCV system
. (Canada) Pull the parking brake lever up. Start the
engine, then check that the headlights are off.
1. Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle,
Connect a tachometer.

1,000, then slowly release the pedal until the engine
idles.
Check idling in no-load conditions: headlights, blower
fan, rear defogger, radiator fan, and air conditioner
are not ope€tlng.

lf necessary, adjust the idle speed, by turning theidle adjusting screw.
After adjusting the idle speed, recheck the ignition

Emission Gontrol System
System Description
Three Way Catalytic Converter (TWCI
\
t
The emission control system includes a Three Way
Catalytic Converter (TWC), Positive Crankcase Ventilation
(PCV) system and Evaporative Emission (EVAP) Control
system. The emission control system is designed to meet
tederal and state emission standards.
InsDeciion
!@@ Do not smoke during this procedure. Keep
any open llame away from your work area.
1. Start the engine. Hold the engine at 3,000 rpm with
no load {in Park or neutral) until the radiator fan
comes on, then let it idle.
2. Connect a tachometer.
Check and adjust the idle speed, if necessary (see
page '11-11 ! ).
Warm up and calibrate the CO meter according to the
meter manufacturer's instructions.
Check idle CO with rhe headlights, heater blower,
rear window defogger, cooling fan, and air condition-
er off.
NOTE: {Canada) Pull the parking brake lever up.
Start the engine, then check that the headlights are
olf.
CO meter should indicste 0.17o maximum.
DescriDtion
The Three Way Catalytic Converter {TWC) is used to convert hydrocarbons (HC), carbon monoxide (CO), and oxides of
nitrogen (NOx) in the exhaust gas, to carbon dioxide (COr), dinitrogen {Nr) and water vapor.

Check the vacuum when hot:1. Turn the ignition switch OFF.2. Block the rear wheels and setthe parking brake.3. Jack up the front of the vehi-cle and support it with safetystands.4- Start the engine. Hold theengine at 3,000 rpm with noload (in Park or neutral) untilthe radiator fan comes on, thenlet it idle.5. Check for vacuum at the vacuum hose with transmissionin gear (A/T in E position,M/T in 'l st gear) after startingrne engrne.6. Ouickly raise the engine speedto 3,000 rpm.
Evaporative Emission (EVAP) Controls (cont'd)
(From page 1'l 147)Check the EVAP purge controlsolenoid valve:1. Disconnect the 2P connectorfrom the EVAP purge controlsolenoid valve.2. Ouickly raise the engine speedto 3,000 rpm.
