1991 Chevrolet S10 Question: Intermittent stall when accelerating
Starts and idles ok. When I hit the gas, it has always had a little bit of a hesitation, but now the engine sometimes stalls when gas is applied. Will not start for about a half hour, then will start up again. Problem is worse under increased engine load such as 4WD. I don't have the rough idle problems and other symptoms that a lot of people report with similar problems. Seems to be getting fuel, not starting after stall persists even when using starting fluid. Cleaned the throttle body with CRC spray. It's not throwing any codes. I'm thinking it could be the MAP sensor but hoping to have a better idea before I start buying replacement parts. Any help is appreciated. - sbell18
