2000 Ford Contour not running very good while idling?

I have a 4 cylinder 2000 Ford contour that is not running very good while idling. It runs just fine while driving, but anytime I stop at a stop sign or I am driving real slow it doesn't run very smooth. It is a automatic and has 175XXX miles it. Any ideas?2000 Ford Contour not running very good while idling?try a tune up my neon did that too2000 Ford Contour not running very good while idling?Again, double check that you Idle Air Control Valve is operating properly. I doubt that it is seeing as how thats a 2000 model with 175k miles on it. Also, take some electrical cleaner and clean your Mass Air Flow sensor. Do that and replace the plugs and wires if you haven't had that done in the last 30000 miles. Double check the life of your O2 sensors. You should be good to go.
