Sometimes when you push down on the accelerator nothing happens. There is no change in the RPMs, If I continue to press down the pedal and release it 5/6 times all of sudden it starts working Again like nothing ever happened. Just the other day the Engine Light came on, I've haven't had time to scan it yet knowing I have more than one rig to use. I'm thinking that it may be time to replace the Accelerator Pedal or the CAT other than this issue, the truck runs great. Thanks for any idea or thoughts on this issue. PS. It's a turbo diesel.

Yep, this happens when the throttle body or the accelerator pedal position sensor goes out, you should run the codes to see which one is having a problem.

here is a guide to help us get started:

Here is how to change out the throttle position sensor assembly. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
