Why is there no throttle response when the check engine light comes on?

My friend is having the same problem. After some research, I've come down to it being related to the idle switch on the pedal assembly. The switch is there because your throttle is electronically controlled and the switch is a canceller. If you release the throttle but the throttle position sensor is messed up and saying that there is a throttle input the truck will try to keep revving. So the idle switch cancels any signal that is being put out by the throttle position sensor. If the Idle switch sticks, it will cancel out your input into the throttle pedal. So when you want to go, the idle switch thinks that your still in idle mode. In a nut shell, people are saying that you need to replace the throttle pedal assembly. It's relatively easy, kind of expensive though. About $220.

Check for a floormat catching on the accelerator. If not the floormat, usually is a mis-routed cable where it comes out of the cable jacket and loops around the throttle shaft. This will hurt you or your engine if left alone-- please fix it quickly. You can check throttle operation with engine off.
