Engine Mechanical problem
2001 Chevy Blazer V8 Four Wheel Drive Automatic
My check engine light went on about 2 months ago and we got a P0440 code. So far the gas cap, purge valve, and purge valve solenoid have all been replaced and the light keeps coming back on. What else could this be. I am a typical girl that knows nothing about cars and has given too much money to too many mechanics already and I still have the same problem. Please help!
