I have a 92 Cavalier. The fuel injector was leaking. Took to a garage for replacement. Mechanic let a piece of injector fall into motor. Motor ruined. Garage found and installed a motor from a 93 Cavalier. Picked up car and ABS light was staying on. This had never been a problem before. Garage ran all kinds of checks on sensors and wiring, could not find problem. Took to an electrical shop for diagnosis. They believe problem may be in the computer! Of course garage says they did nothing to computer and don't want to replace that because they didn't touch the computer. I do know they had the right front wheel off. I don't know about the left front. Aside from re-checking all the connections at the sensors, is there any other place to check for loose or bad connections. Also, is there a way to reset an ABS light?
