Answers: when i bought my jeep Cherokee, the check engine light be on. the dealer told me to bring it contained by the next morning and they would check it for me. It was the gas sunhat that was messed up. they put a up to date gas cap on and everything have been fine. not dictum that is your problem but it basically shows that it could be anything at all i.e. wrong
