Engine Performance problem
1990 Cadillac Deville V8 Front Wheel Drive Automatic 108000 miles
I just bought a 1990 Cadillac Deville, It has sit for about 7 months and the car requires premium fuel but the past owners were putting mid grade fuel in the car for several years.
I’m starting to get a rough idle and backfire when I press on the gas, also when I sit at a light and I also get a stall and loss of power when I press the gas pedal while driving. Sometimes it clears up and the car runs great. Do you think this is because of the gas, fuel pump, or something else?
have the same problem?
