1990 C2 hesitation
 

HI,

I have a 1990 C2 cab with 92K miles. It runs great under full throttle acceleration. At constant speed when I back off the throttle then lightly accelerate it hesitates, the peddle actually goes dead for a second or so then it catches again. It also does a similar thing when starting off from a dead stop and mild acceleration. It will start off fine then the peddle goes dead for a second then catches again.

Looking for help? Throttle position sensor? Flow sensor? Brain?

Has anyone had similar prolems?
