I HAVE A FULLY REBUILT D16Z6 SINGLE CAM VTEC MOTOR.. I SWAPPED IT IN AND TOOK MY OLD D15 MOTOR OUT.. THE ONLY PROBLEM IS THAT IT TURNS ON AND EVERYTHING SOUNDS GOOD BUT AFTER A MIN OR TWO IT BEING ON IT STARTS TO REV UP BY ITSELF AND THEN TURNS OFF... WAT COULD THIS BE??????

 

dont use caps lock. its annoying. and give more info. how high does it rev. does it get hot/overheat?

 

no it doesnt over heat or nouthing and it only revs up to 3 and stays there for a bit then it shuts of...

 

Vaccuum leak?
