I have a 1990 buick century v6 3.3l a while back the service engine light kept coming on so I ran a diagnostic on it and it came up fault 26 in the computer. I recently switched computers on the car with one I got from a scrap yard. My question is do I switch the computer chip from my old car to the new computer or leave it alone? Any help is appreciated thanks.
