Testimonial: "Thanks helpped alot!"
I would suggest stopping by an AutoZOne or O'Reilly's and "borrow" their Scan Tool to erase any codes.
TO reset the "Change Oil" light, turn the ignition to ON (do NOT start the car). Press the accelerator pedal all the way down (then release) to the floor 3 times in less than 5 seconds. Change Oil light should flash then go off. If not, try it again. The trick is to get this done in 5 seconds ro less.
