Hey r81ders you got a beautifull truck...I m having the same prob with mine. The truck was running awsome till i limped it a couple of months ago. I changed the fuel filter, tranny fluid, and air filter and i thought it was running fine till i pulled my trailer on a long haul. It actually runs a little better when i pull the diablo programmer off of it. Going to take it to the dealer and have them check it out. They also told me nothing was wrong with it the first time i took it in.
