ls4 Misfire (cylinder 6)


Protection

Recommended Posts

Flashing CEL, Smoke at all rpms EXCEPT in AFM. I know cylinders 1 4 6 7 or AFM cylinders. I am thinking the is still active on cylinder 6 full time. Stuck or something. I also had the code for the oil pressure switch yesterday, replaced it.. Cleared the code and hasn't came back. The p0306 code for the misfire is still there though. I changed that plug (oil fouled) and still no difference. The engine makes a noise at idle and idle only almost sounds top end and like a metal plate is loose. I knew I should have got AFM tuned out sooner.

Well getting the AFM tuned out fixes the oil consumption, but im figuring I might be too late.. since I have no moneys for expensive tune. but its not burning oil in the 100+ miles ive driven it since ive noticed it. still around the same level. I the way its smoking and the flashing light im thinking its fuel burning.
