Engine Performance problem
1997 Chevy Blazer 6 cyl Four Wheel Drive Automatic 110000 miles
My Blaser will run fine for two days (100 miles worth of driving), then it will cutout when I let off the gas as I'm driving down the road. It immediately picks right back up again but will continue every few seconds. RPM drops off during this time. It will be bad enough to stall when you come to a stop. I had the garage look at it and they couldn't get it to act up, then I stopped in when it was acting up and they quickly put there analyzer on it and they said it was calling for a significant amount of fuel, much more than it should be. They suggested the Coolant temp sensor ( because they thought they saw the temperature fluctuate, I did not see this) or the EGR valve. Here is a list of changes made over the past few months:
- changed coolant sensor
- changed EGR valve
- changed Igintion switch
- changed Fuel Pump & gas tank because of a leak
- changed 3 spark plugs & wires (just haven'y gotten to the other 3)
- changed heater blower (because it failed)
still no help. Again it might go 2 days before acting up then its almost undriveable. Any info would be greatly appreciated.
have the same problem?
