Why would a 1999 Ford Contour shake or vibrate at idle?
I also wish someone would answer this question as my 1997 Ford contour does the same thing. It shakes and vibrates very bad when it idles and it idles really low.

Ford f-150 idles fast?
If you have a carburetor, there is a crew on the driver side behind the throttle cable it usually has a spring on it if you turn it to the right it idles up left it idles down If its a fuel injected motor idle is handled by the computer. There usually is a "base idle speed" around 800-1000 RPM. This normally doesn't need to be adjusted. Have a look for carbon build up on the butterfly as well, this will influence idle too.
