Has anyone come across an e38 ecm failing.I have a series 1 VE clubsport at work and its doing a few strange things.The car is std and untuned.On startup it rus terribly and first the trac cont light comes on then the check engine light. If left running for 20 mins or so it will run sweet .It comes up with a cyl miss fire code(300) if cleared it will come straight back but not always the same cyl.When it misses the cylinder is dead but still has spark and the injector is pulsing. tested all the sensors etc. All of the sudden it will clear itself and run sweet until switched off and left overnight then same problem.Any ideas?It doesnt have dod. comp are all the same injectors fine fuel clean, pressures ok.Im thinking ecm but am curious as to whether anyone else has had this happen?
Cheers Shane
