I have a 1981 Chevy Luv 1.8L 4wd gas truck. It has been running great but all of a sudden it began back-firing and the engine quits. It does this whether hot or cold. It starts and re-starts easily but I have to keep my foot on the gas pedal to keep it going else the engine dies. The idle is either too slow or too fast. It won't Idle, really, meaning it won't keep running without my foot on the pedal. After this problem began I changed the fuel filter but that did not affect anything. Thanks so much for your help.
have the same problem?
