The ignition coil pack in your 1996 Chevy Cavalier comes equipped with a double coil, each one connecting to two spark plugs in the engine block. A single faulty coil will provide a weak or no spark to two of the block cylinders. However, the pack configuration allows you to replace only the faulty coil, without the need to replace the whole assembly. Better yet, you can remove the assembly from the engine and install the new coil at home with a few tools. These instructions apply to the 2.2L engine model.
Separate the negative (black) battery cable from the battery post with a wrench.
Follow the spark plug wires from the spark plugs in the engine block towards the opposite end to locate the ignition coil pack. The coil pack is mounted on the engine block, right in front of the firewall and under the intake manifold.
Label the spark plug wires with masking tape and a marker so that you replace them on their corresponding coil towers during reassembly then unplug the wires from the coils.
Shift the transmission to Neutral and raise the front of your Cavalier with a floor jack. Support it on jack stands and block the rear wheels with chocks.
Put on safety glasses and climb under the vehicle. Unplug the electrical connectors at the ignition coil.
Unfasten the three bolts holding the coil pack assembly to the engine block with a ratchet, short ratchet extension and socket. Remove the assembly from the vehicle.
Replace the coil or coils from the assembly with the ratchet, short ratchet extension and socket. Install the coil pack assembly onto the engine block with the same tool combination.
Plug in the coil pack assembly's electrical connectors then lower your Cavalier with the floor jack.
Plug the spark plug wires into the coil pack towers and reconnect the negative (black) battery cable with the wrench.
