Your engine has severe blowby. The piston rings need to be replaced or your engine replaced. The excessive blowby is probably fouling out your spark plugs.

Spark plugs

The spark plugs on the cavalier are under the 2.2 ecotec panel located on the top of the engine. There are no spark plug wires to deal with. The electronic coil pack directly attaches to the plugs with rubber seats like in a spark plug end. Then you use a deep socket ratchet to get the plugs out. Use anti-seize compound when replacing the plugs.
