'99 F-250 7.3 NO THROTTLE

My truck is stranded in a friend's driveway. The truck will start up and idle fine but there is no throttle when you hit the gas. When you hit the gas the SES light comes on until you let off and then it goes back out.

All fuses check out fine and I have no way to hook up a scanner to it.

It turned out to be the idle validation switch. (I think the pedal position sensor was on it's way out too).

On the IVS there is a little metal tap that pushes in the button on the switch when the pedal is pressed. Well that tab started to fall off and was ****ed to the side so it wasn't even touching the button when the pedal was pressed. I stick my finger in there and bent it back and it is working again for the time being although it is so loose it could come off again.

I ordered the complete pedal assembly from the dealer ($170). I think they gave me a deal because we originally bought the truck there.

Anyway, NAPA has the pedal position sensor ($60) or the whole pedal assembly ($230) but the IVS can't be had by itself.

It is amazing that something as small as that stupid little metal tap can keep the entire truck parked for a week...
