Engine Performance problem
1994 GMC Sierra V8 Two Wheel Drive Automatic 206K miles
The truck would lose power initally with the "check engine" light on. Within 100 miles or less the power loss was more dramatic, to the point of barely able to move. I could pump the gas peddle and get some power, but not much. The engine seemed to idle nicely for a while, the cut off, especially at the end. The engine will turn over and start well. The truck sits most of the time, water in the gas? Electronic ignition module? Fuel pump? How do I test the (in-tank?) Fuel pump in my basement? Could I be completely off the mark? One note; the truck would run just fine at first, but when the "check engine" light would come on, the power loss would start. Waiting for the truck to cool down did not help.
have the same problem?
