Hello,
I am looking for help with my cylinder 2 misfire that has been bugging me for a few years. The car needs a clutch/main seal soon so I thought id tackle everything at once. Engine has ~250k km on it but it has fairly good compression numbers on it so I don't want to rebuild it.
It is a 5SFE with distributor and single coil. Ignition timing is not adjustable (I believe it is controlled by the ECU)
Things I have tried:
Spark plugs
Spark wires
Distributor cap and rotor
New PCV valve
Cleaned EGR valve, passages and vac hoses
Swapped coil packs with another car
Swapped injectors around
Compression test (185psi +/- 5 psi for all 4 cyl)
Seafoam
Cyl 2 used to have a leaky valve stem seal that has been fixed. I am guessing there could be more crud in this cyl. Would this be something that the compression test would pick up?
Fuel trims look normal. Misfire and stumbling is rather intermittent. Some days it will noticeably shake and some days it drives very nice.
Any pointers would be great! Thanks.
