There are two ignition coils on a 91 Cavalier. There are both mounted on the back of the engine block (firewall side). While they are difficult to reach, they can be removed & replaced in about an hour to hour and a half. A small mirror with an extension handle is helpful for getting your bearings on the two small mounting screws on each coil. Be sure and keep the spark plug wires marked so they can be put back in the right place for the firing order
