Engine Slightly Choppy Idle And Smells Rich Too

[cdurbin]

Quick question for the experts. I noticed my car idles at around 650-750 but it has a slight chop to it.
It kind of lopes just a hair. Nothing major. It doesn't die or anything like that. Also it smells pretty rich too. Any ideas on this or is it pretty normal? This is my first Fox so I'm still figuring things out.
Thanks

It's normal if you got some miles and age on the stock components. Sound like it's tune up time. New plugs, wires, cap, rotor, fuel filter, oil filter, PCV valve and O2 sensors would do you good.

Ok, I just replaced the plugs, wires, cap, rotor, and oil.
Going to change the PCV and gas filter this weekend.
Forgot about the O2's though.
Thanks

Check for vacuum leaks.

See the "Surging Idle Checklist” for help with all your idle/stall problems. You can guess at the problem and throw parts at it, or you can use the checklist to help you find the problem quickly and inexpensively. The checklist is right here in the Stangnet 5.0 Tech forum and you don’t have navigate to some other unknown web site. It‘s free and doesn’t cost anything: at last count there were more than 103,000 visits and still climbing

The quick and easy way to dump the codes is in there too, and all you need to do it is a paper clip! The first two posts contain all the fixes & updates. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.
