I have a 2012 chevy malibu, automatic transmission with 180000 miles, recently my niece my driving my car. She has it on park got into itand reved up the engine. It started to smell like gas and engine power reduced came on, the engine was vibrating and the p1682 came on. I changed accelerator pedal sensor. Throttle body and camshaft sensor. Took it to electrician and he couldn't figure out what was wrong with it. Took it to dealership and the said it was motor mounts. I can't afford to take it and them "guess" what it is and me continue to pay and not getting the problem. I need help
said to tell you the truth but those are pretty junky cars and when she rubbed up the engine she may have blown the head gasket have a pro check that as in my video how to tell if your head gasket is blown
