My Lincoln starts fine but will not idle. Runs fine driving with foot on gas. Take foot off gas it stalls what could be the problem could it be my throttle position censor or needs new fuel filter. If it is throttle position censor were do I find it located on my car. Thanks

Clean out the idle air control valve and see what happens

Here's a little more detail on what Ras is suggesting.

You may have a bad IAC ( idle air control) but try eliminating any vacuum leaks and cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
