On a very rainy day, I got some gas from the Shell and 15 miles later, my check engine light starts flashing and my car starts shaking as I accelerate.. Pulled over to the side of the road and my exhaust smells like I just fired off some fireworks.. Exhaust from the tailpipe is colorless... Took it to auto zone and I get the code for multiple misfires, system too lean, torque convertor sensor stuck on "On",and something about my fuel gauge.. Please give some idea of what wrong so I don't get highway robbed by a mechanic lol..
What is causing my check engine light to flash? on 2004 Chevrolet Impala
tell us what the code was and check to see if your gas cap is on right
