Yeah, pop the big fuse panel cover off and you can look right at it sitting on the top left side of the pedal. I took pics of my progress and will get them posted in a bit.
ok. here are pics, and a huge thanks to Russtwentyfour!

there is a flat tab coming off the pedal that goes into a slot in the sensor and makes a 90 degree twist. Turning it by hand there was a sticky spot right off of 0, and flaky slippery spot at about 45 and a hard sticky spot at 75-80 degrees and it would hang up and have to be forced back down.
I filled the turnable slot with contact cleaner and twisted it back and forth for a couple of minutes with the screwdriver.
after a couple of minutes of turning it, the sticky spots went away, and there is apparently a spring return inside the sensor which actually started working again once the crud was cleaned up.
i kept turning it after dumping out the excess contact cleaner until it dried, then reinstalled it.
truck works beautifully now.
I didn't realize it but the inch of deadzone at the start of pedal travel wasn't normal and the truck actually takes off without having to floor it. Still no hot rod, but not quite as much of a dog as it used to be.
the contact cleaner i used was: LPS Micro-X fast evaporating contact cleaner which is labeled safe for plastics
