TPS throttle position sensor- I have had problems with mine a couple times. You can change the whole throttle pedal (expensive) or just the tps (it unscrews from the throttle pedal with 2 "star" screws). I've bought them on ebay for $15.00, and it shows the same one for the F150's also.

Also check your fuse's. I had the sample problem and turned out to be a fuse, Good luck.

What he said. I beleive it was fuse #13 under the dash. You can tell if it is the fuse tho by the amount of lights on the dash when you start it. No Wait TO Start, and dash gauges won't work.

This what the pedal looks like. The Smaller switch with red is the idle validation switch. You may be able to get them going with some contact cleaner or something similar

What turned out being the problem? We love hearing what it took to fix the problem. Nothing's worse then reading through a thread only to have it dead end without a solution.

So far i lubricated the switch,so i'll have to drive it.The only problem i drove it earlier and it did not screw up!I will be getting back to you to tell you if the cleaning and lube fixes it or a new TPS switch.

I have tried that,forgot to tell you guys that.One other thing,it seems to happen when the truck gets to around a quarter of a tank of fuel.The wife allways hates to put fuel in it.Could there be a sensore in the tank that could do this.A couple of times the low fuel light came on too.I would get it to the station,pain in the ***,put fuel in it and it would still have to sit for a little bit to get to work again.But this is not all the time

Yes it would help knowing the code. The 1/4 of a tank thing. Is this a different problem to the pedal.
