The symptoms the car has is that it revs itself whenever moving, up to about 3k. If you are standing still, it idles normally. TPS voltage is flutuating, I'm getting between .8 and 1.1 at idle, its different everytime you start it. It tends to work fine if you start it cold, drive it, turn it off, then start it warm. After its started warm, the car no longer revs. Any ideas? 1998 Contour SE 2.5L Duratec DOHC 5spd.

If you come to a solution I would be interested in hearing what you did. My problem was that every once in a blue moon it would throw a P0122 (TPS low input) code.
