OK, so I just bought a used truck form a dealer a week ago. Yesterday
morning my check engine light comes on so I bring it in to the
dealership today and they check it out. They tell me that because the
truck has aftermarket dual exhaust it is getting a false reading and
the light comes on for no reason. This somewhat makes sense to me but
am curious as to everyone elses opinion. Is this a commom problem? Or
should I be worried?
