    is that the same motor that came out of it? If you installed another year or type of motor, the computer will not know this and is running the data for the original motor that was in the car, so everything will be out of wack. Check the ignition timing, and recheck all the connections to make sure everyhting is hooked up right. Ensure the spark plug wires are in the right cylinder and distributor position.
