my car has a miss/stutter and it is very iratic, not in pace at all sometime it does it , then it doesnt.. i just did a tune up yesterday and the back 3 plugs on the pass side were almost white . so the question is do i have an o2 or an injectior problem, the o2 are about 2 weeks old. help i"m going insane and dont really have alot of extra cash to be just repacing parts

EFI plugs normally run fairly white, so that might not tell you anything useful. Code scan will be more useful if changing the filter doesn't help. O2 sensors are seldom the cause of a lean or rich code, more often than not, they are providing the correct information and telling you something else is wrong.86 Lincoln Town Car (Galactica).

your plugs should all be fairly consistent in condition.. if 3 of them looked alot different than the others they could have been gapped different or indicating a lean condition.Give a man a fish and he will be fed for a day.

You've got them gapped too small. It should be .052 I believe. Its on the emissions sticker under the hood, right next to where it specifies the plug type.86 Lincoln Town Car (Galactica).

ok im lost , i feel like im chasing a ghost , i changed the injectors and regulator then put in new plugs and even set them to oe spec instead of 35. and the car ran good other than it surging because i cracked the egr vac line. i fixed it and the car runs great then im on my way to work this morning and sitting at the light it stutters/misses again ... so now what im losing my mind . and contaplating just parking it in the gurage and letting it rust in peace.sigpicTHE H.I.D MASTER
