Asked by Nov 08, 2017 at 06:05 AM about the 1993 GMC Sierra C/K 1500

Question type: Maintenance & Repair

I have a 1993 gmc k1500 4wd pickup with the 5.7 throttle
body. My problems started to occur when I would let off
the gas it would sound like it was dieing but never would
actually die but hey the truck kept running so I never
worried about it. It was a normal day the truck was
running fine I got home from work went to crank it back
up and it wouldn't crank it was flooding itself out or
getting to much fuel so the next day I walked outside I
cranked it the truck ran like a dream then I killed it and my
problems started all over again like it's dumping to much
fuel. Parts I've changed already ( map sensor, TPS,)
