Off-idle hesitation
02, OHV, 130K, burns no oil, runs great.
This recent, off-idle hesitation when accelerating from a stop only occurs at normal operating temp. Car accelerates normally when engine is cool/cold. Pulled one of the plugs I installed about ten years ago and it looks brand new! No color whatsoever on the insulator. Air cleaner is relatively new, fuel filter change at 50K also cleaned the mass air flow sensor not long ago. Clearly it's running lean off-idle, but why?
Tanks yeah.
