I am getting a misfire in cylinder 1 when i first start the car on a cold morning and let it run for a couple min. i have changed coils around to try and narrow down where its coming from but it still continues to misfire on the same cylinder. any ideas?
Mis-Fire Next most likely thing is the ignition coil wiring harnesses, especially as this has been a problem on a number of E46's.Also change the plug just to be sure. Good luck
