Engine Performance problem
1999 Chevy Suburban V8 Two Wheel Drive Automatic 110, 00 miles
I changed the fuel pump about 2K miles ago. Was driving fine but then then when going about 40-45 MPH the RPM's would drop to 1500. It will climb back up again after I press the gas pedal. This was not a problem until the car stopped after sitting at a busy red light. Would not restart and finally drained the battery from trying to hard. After finally getting someone to help me started right up with a jump. Took battery to auto parts store, battery was fine. The car keeps on starting and going with no problem except for the drop in RPMs. Thought that the Fuel Pump Relay might be bad so I changed that. But the RPMs keep on dropping at that same 40-45 speed.
Do not want to change fuel pump again, any other ideas?
have the same problem?
