Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if the check engine light is coming on when this occurs? Does it seem to be worse when the engine is hot or cold? Does it ever run perfectly fine?
Thank you. It sounds like you may have an internal engine failure or it may be a bad sensor. When was the engine last tuned up? Do you have a vacuum gauge to run some tests?
