The light came on today after driving about 20 minutes.
I sprayed the heat shield bolts with PB Blaster last night, in preparation for my header install next weekend. I probably got some on the O2 sensor fitting. Is this the problem? I know that the check engine light is linked to emissions stuff, I just need to know if I should take it to the dealer or a mechanic to get it checked out.
TIA
