Engine Performance problem
1992 Chevy Truck V8 Two Wheel Drive Automatic 125000 miles
Truck acted like it had no power. Rough idle and would die at times. During power braking, it would back fire sometimes. Replaced distributor cap, rotor, spark plugs, fuel filter. No better.
Took to shop they replaced fuel pump. Ran truck for hour over different driving conditions. Ran fine. Daughter borrowed truck. Ran fine. She filled truck up(20 gal of 32 gal tank). Ran for 20 minutes, then lost power.
Exwife went to drive truck home. Ran fine. Put in new battery and had altenator checked.
I went to look at, replaced coil and spark plug wires. Started truck, idled fine. Went for test drive. Ran fine. After waiting for light, took off, truck lost power. It also sounded like engine was pinging. Pulled over into parking lot, turck died. After waiting a minute, started truck, ran fine.
After driving for a minute, same symptoms. If I put truck in 1st gear, it would buck and ping then clear up and drive fine for another minute or so.
After getting back to their house, opened hood. Motor smelt hot, but showed fine on temperature gauge.
have the same problem?
