Try to turn the key in the on position do you see the light lit? If not replace the bulb and get those code's read and you will find the problem. Also 2000 RMP is to high see if there is anything holding the throttle open. And if there is a idle screw lower it. _____________________________ 94 4x4 ranger (in reply to danny88) Post #: 4

The gas pedal is fine 'cause in neutral the car is fine. One quick question though, if the valves are sticking, either one, intake or exhaust, would it cause this problem? Thanks.

If you look at the throttle body where the idle set screw goes does it rest along it when the throttle is closed? Basicly what im trying to say is the throttle closed all the way at idle? _____________________________ 94 4x4 ranger (in reply to danny88) Post #: 6
