Misfire Cylinder 6 at Idle

1BADM3 · 09-17-2016, 10:51 PM

I am getting major misfire in cylinder 6 at idle and while driving. Sometimes it will clean up doing driving but idle is terrible i even pulled the plug of cylinder 6 while the car was on and it had no effect. I replaced coils and spark plugs did a compression test got 110-115 throughout all 6 cylinders. Spark plugs look pretty bad before i pulled it.

Before this happened i was getting small misfires at WOT.

Cylinder 6 is at the top.

Any fuel smell on it ?

Leaking injector would be my guess.

soot means unburnt fuel. I have my money on the injector being bad
