Engine Performance problem
2000 Chevy Impala 6 cyl Front Wheel Drive Automatic 166000 miles
My wifes 2000 Impala has begun to surge while driving with a constant throtle. If it begins to pull a little hill, it will surge from about 1700 rpm to 22 or 2300. I have replaced the fuel filter, fuel pump, fuel pressure regulator, plugs, and wires and have not found the source. The car is also not tripping any codes! I am completely at a loss now. Please help!
