I just got the car back from the shop for it dying out they replaced some sensors on the distribetor and put a new sensor in the oil pan... My uncle drove the car home he said it ran fine but soon as he pulled in the drive way the check engine light and oil light came on. He turned it off came out 15 mins later cranked it up and no lights except airbag light. Is this just a sensor problem or computer or am i lookin at a major problem here?
