All seemed great yesterday afrs were where the should be around 14.7 so I parked it and then while driving to work this morning guess what came back! The lope in the idle.

Agghh. The CEL did come back on and I will be checking that at lunch time and will update that info. I have no idea what's goin on.


Is it possible my headgasket is seeping? Although I am not missing fluid.



I put some new fuel in it with some injector cleaner so time will tell of that helps at all.

Per my post above, have you checked for boost/vacuum leaks yet via pressurizing the intake yet?
One potential issue is a split vaccum (or charge air) hose that weakens with heat. A boost leak check will detect this (and an ordinary smoke test won't).

Here's another thought (while we're on the topic of split hoses):
