I have almost the same friggin’ issue right now. Have an 07’ redline with 34k on it.I have an ‘08 Redline, 34K miles. Check Engine Light always comes on after reset. Takes about 60 miles of driving. Code shows all cylinders misfire at low RPM. Code clears when aggressively driven. So far...new AC plugs, 4 new coils, intake induction cleaned, fuel additives, new gas cap, same code appears. Also did a smoke test for leaks. Nothing found. Kind of frustrating. Any help is appreciated.
From cold start at idle check engine comes on coding multiple codes here and there. P0302, P0301, P0303, p0300, and a weird P0000!
I mean here and there cause I clear the codes with scan tool and usually it’s P0302, but this last time 6codes came up and stating all the ones previously mentioned.
I had it at dealership recently and they were stumped, paid for them to high pressure clean fuel rail, jumped in to drive away and check engine light turned on with P0300 codes.
Car is stock had a L&T air filter but in trying to figure out issue placed a stock air filter in and cleaned maf sensor. Dealership said possible injectors... but so random.. I can see if just same code, but codes jumping, and only at cold start and only after clearing codes it trips code again after about 100km of driving and again on cold start...
Haven’t really noticed a difference in performance.
Please help, any suggestions! Dealership checked over car(head gasket, vacuum, spark)
Cam sensors?? All of them at 34k??
