    05 GTO, Will not stay in Closed Loop

    I have been watching my 05 GTO while driving, the dashhawk shows fuel mode, and lately i have been looking up to see it in open loop.. then it switches back to closed loop...

    I thought it was perhaps a dashhawk firmware error, so i finally logged it with HPTuners tonight, and it is indeed showing OL during some of my logs...

    I will post the HPL and HPT in a few minutes...

    I have Longtube Headers, Catless Mid's, H Pipe, Spintech Mufflers, Ported Throttle Body.

    This phenomenon occurs on some GTOs when you change the Engine Diagnostic code settings. I could never get it to happen on MY GTO (though I tried) ...

    ... the car is going into "Lean Cruise" ...

    Read the 2nd to last post in this thread ... he explains how he stopped it from happening:
