Always something with this damn engine....
So now I have a slight run on whenever I shut the engine down. More so when ECT is at operating temps, than when cool. I have not had this happen before.
Changes that I've done are new ID 1000 injectors, and a complete re-cal of VE and MAF. I haven't touched idle speed, and min air is the same. Trims at idle are under 5%. Idle spark is 18. Idle speed is 900.
I could just start changing things and see what might cure it, but figured I'd get input first. I do not think it is detonation, but run on. My initial thought is to just reduce idle speed to 850. It's at 900 to help get the car rolling from a dead stop without having to feather the throttle so much. (08 Z06 with a healthy cam). It will idle at 800 OK...just a lot of lope.
