Question about Cadillac Catera
Have you got a check engine or maintenance light showing on the dashboad? If yes then you need a diagnostic test done which will retrieve some error codes. Once you get the code then you can start troubleshooting as it will point you where to start. Otherwise it will be like looking for a needle in the ocean.Hope this helps,good luck.

I am assuming that you have a cylinder #4 mis-fire, and that there is a data trouble code P0304 (cylinder #4 mis-fire detected).
An electrical mis-fire is what I would suspect to be the problem, and it is most likely caused because the coil pack is defective or malfunctioning, and I have had many problems with those coil packs. Also the #4 spark plug could be fouled out.
A mechanical mis-fire can be caused by a leaking intake manifold gasket, a vacuum leak at a fuel injector seal, or a bent or burnt valve in the cylinder head.
You should replace the coil pack.
