1991 s10 blazer 2 door 4.3l automatic
4x4
ok i bought this truck about 2 months ago. immediately had the fuel pump changed. (was bad)
about a week later the truck starts to bog on me when i drive it at low rpms. i have to hit the gas pedal down about half way to get it to move. sometimes hear a small popping sound. it doesnt happen within the first 5 or 10 minutes of driving. after the first 10 min. the bogging starts. sometimes the check engine light comes on and it runs better but not as good as the first 10 min. of driving it from a cold start. i dumped some injector cleaner in the tank and sprayed the hell out of the injectors. did nothing. any help would be greatly appreciated
