My Escort idles very rough. When driving, the engine seems to perform OK, but when coming to a stop, or when starting the engine (while still in Park), the engine idles rather rough.

It has new air filter as well as spark plugs and wires. I have run off-the-shelf fuel injector cleaner through the engine. I'm thinking either fuel filter or PCV valve. Make any sense?
