Engine Performance problem
1991 Chevy Truck V8 Two Wheel Drive Automatic
The truck runs great for 20-40 minutes then starts backfiring. I think raw fuel is in the exhaust . It back fires so hard it splits the mufflers right down the seam. this only happens between1500-2500 RPM and it has to be under load.
