I believe its a 2004. Had the oil changed yesterday. and today the check engine light came on. took it to auto parts place, they hooked it up and said it was clear and no codes came up. could it have been the oil change? should i take it to a mechanic? it also started to make a rather loud rattling sound, but that was before the oil change, and it only happens sometimes.
are you sure it isnt the service engine soon light that came on? This means you need to reset the oil change monitor system in the car .the directions on how to do this should be in the owners manual. Also i would try an actual reapir shop to check the ecm for codes, i dont trust these guys in auto part stores very much. gl
mis fires at times can make the light come on, however unless it is a complete dead miss they usually they will not register a DTC code in the system. That possibly could be the issue. I have never heard of an oil change causing an issue with the check engine light. good luck
