2002 Grand Prix GTP is in limp mode (is there a limp mode for 97-03?)
At more than half throttle, the car behaves as if it's hitting a rev limiter. Drives
without issue under half throttle, both from a start and cruising.
I have a MAF code P0102. I've removed and cleaned the MAF with sensor
cleaner and the issue remains. I guess I'm looking for confirmation, or
suggestions as to if it could be anything else.
