LXnSHO, I wasn’t trying to imply anything there, hopefully no offense was taken, just that those codes don’t kick the logic out of closed loop, and I don’t think timing or fuel is affected…. Not directly anyway…. Again, haven’t looked at that info in since around 2006, lol

I agree with you. I was thinking hard as I cannnot fully justify the difference in driveability.
Actual picture of deep thinking.
