Got my oil changed and now my 'check engine' light is on.
I got my oil changed on Thursday and ran several errands afterwards with no problem. When I started my car Friday morning, the "check engine" light came on. I ran several errands that day and each time I started the car, the light was still on. Is it just a big coincidence or could they have done something when I got my oil changed that would cause the light to come on?
