miss firing at idle

[joebomb]

when my car is sitting there idling it misses. you can hear it at the muffler. the car runs great but only at idle does it seem to miss. i had it checked out and the engine code was cyclinder 4 miss fire. i replaced the plugs, wires, distributer cap, and rotor. i also had a professinal fuel injection cleaning. i dont know what to do.

TheMan: Is this a 2nd gen specific problem (misfire 4th cyl)? I remember reading something similar to this several times from other 2nd gen owners.

check your timing, and if thats fine... the plug/wire on cylinder 4.... and if thats fine do a compression test
