Seems to me that I asked about this before. My problem is semi-solved. Turns out, it was caused by corrosion, at the pedal pivot pin, while during my stint as a Contractor supporting Warfighters, and the truck was neglected. I seem to recall someone sending my a picture of a bungee installation, of which I'd like to use, while driving, after I've cleaned and lubed the mechanism - it just needs a little "help". Does anyone have that pic, or are using that concept, now? It's only temporary.
