Spark Plug Inspection
Inspect the electrodes and ceramic insulator for:
. lmproper gap. Oil-fouling. Carbon deposits. Cracked centerelectrode insulator
Burned or worn electrodes may be caused by:
. Advanced ignition timing
. Loose spark plug
. Plug heat range too hot
. Insufficient cooling
Fouled plug may be caused by:
. Retarded ignition timing
. Oil in combustion chamber
. Incorrect spark plug gap
. Plug heat range too cold
. Excessive idling/low speed runnang
. Clogged air cleaner element
. Deteriorated ignition wires
I
2. Check the electrode gaP.
. Adjust the gap with a suitable gapping tool.
Electrode Gap
Standard 1.1 3 ' mm (0.043 Loo. in)
Replace the plug if the center electrode is rounded
as shown below:

Apply a small quantity of anti-seize compound to
the plug threads, and screw the plugs into the cylin-
der head finger-tight. Then torque them to 18 N'm
(1.8 kgf.m. 13lbf.ft).

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
YA8845-2A 7/8" auachment). Use approved eye protec-
tion.
1. Turn the crankshaft so that the No. 1 and the No. 4
pistons are at top dead center (TDC).
2. Remove the cylinder head cover.
3. Remove the distributor.
4. Loosen and disconnect the timing belt from the
camshaft pulleys.
5. Remove the camshaft holder bolts. then remove the
camshaft holders, the camshafts and rocker arms.

6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the top hole of the
two uprights,
at.
9.
Select the 7/8 in. diameter long compressor attach-
ment, and fasten the attachment to the front hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing the
springs and removing the valve keepers.
10. Put shop towels over the oil passages to prevent
the valve keepers from falling into the cylinder
head.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown,

Select the 7/8 in. diameter short compressor attach
ment, and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.

Misfire Detected in One Cylinder
Ipffi1] Thescantoot indicates Diagnostic Trouble Code (DTC) P0301: Cylinder 1 misfire detected.

lF0il04l 16" ""un tool indicates Diagnostic Trouble Code (DTC) PO3O4: Cylinder 4 misfire detected
Description
Misfire detection is accomplished by monitoring the crankshaft speed with the crankshaft speed fluctuation (CKF) sensor
which is attached to the crankshaft.
lf misiiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence. and DTC
P0301, P0302, P0303 and/or P0304 will be stored. Then, after the misfire has ceased, the MIL will come on.
lf misfiring that increases emissions is detected during two consecutive driving cycles. the MIL will come on, and DTc
P0301, P0302, P0303 and/or P0304 will be stored.
NOTE: lJ some of the DTcs listed below are stored at the same time as a misfire DTc, troubleshoot those DTcs first, then
troubleshoot the misfire DTC.

P1336, P1337: CKF sensor

Possible Cause
. Fuel injector clogging, fuel leakage, air leakage
. Fuel injector circuit open or shorted
. Spark plug carbon deposits, fouling, malfunction
. lgnition wires open, leaking
. Distributor malfunction
. Compression low
. Valve clearance out of specification
