P0306 - Cylinder 6 Misfire Detected


Check the spark plug wire.. When was the last time you changed the wires?

op states plugs, wires, coils are good. i also have good compression. still have a misfire

Check the coil packs make sure the contacts are not corroded. If all are good as you suggest, I would replace the ICM under the coil packs.

cool ill loook into that im pretty much at a dead end

I would also swap the coil locations and see if the misfire follows, if it does then you either have a bad coil or wire.

2nd guess would be a some-what clogged fuel injector

so i swapped coil and ran half a can of seafoam in a little over a quarter of a tank and went for a very spirited ride. laid on it from 20 to about 80. no missfire. but the car smelled alot. why would that be?

probably because your burning out a lot of the stuff clogged in the injectors. And that is a pretty strong mix for sea foam in a vehicle. Or at least it seems like it.

i didnt think that i just thought because when this all started. i had just bought the car, drove an hour home carefully because i had swapped plates and bought out of state. so my girl was behind me on the last stretch of highway home i layed on it from like 55 to maybe 70 and it misfired and she said it reeeked but didnt notice alot of smoke. then last night when i took it out she was with me. i layed on it a couple times and it smelled. and she said thats how it smelled before when it happened. i feel like at idle it smoke a lil bit more than normal.

I hate when exhaust smells like burnt hair. YUCK. Wouldn't most cars smell under a heavy load? I always notice on the road if someone passes me, I get a whiff of stink if they are giving it (new and older vehicles).
