No acceleration

It sounds like the engine went into Reduced Engine Power mode. Since the H3 is a drive by wire, it monitors the commanded throttle position (accelerator pedal) using two sensors and the actual throttle position (throttle body). If the commanded postion is different from the actual position -> Reduced Engine Power mode. The vehicle will just limp along in this mode. When you restarted the engine, the PCM found agreement between commanded throttle position and actual throttle postion and operated normally. You can either have the code cleared or it may clear on its own after XX number of driving cycles.

Thanks for the info guys. Today the check engine light was on for a while. It did go away after a few stops. Taking it in tomorrow to have everything checked out.

Kracker .. curious, did you find out what was wrong with your H3?

my Audi TT used to go into limp mode all the time, a real pain. Usually happened when someone was messing with me too lol. Of course I was running 25psi of boost
