Re: 02 Crown Vic Police Inteceptor running rough
Personally, I would start with a tune-up. Plugs, wires, filters, etc. Check to make sure all cyclinders are sparking, and that the injectors are going (use a long screw driver, tip on top of the injector, handle at your ear. You should hear a tapping sound even across all injectors). Find the source of your engine code. If it's an exhaust leak, there's usually the tell-tell signs of black soit build up where the leak is. O2 sensor should be checked. The 'miss' could be a combination of things.
