I'm pretty sure it's a condition called "cam surge" It also affected some of the early Fbod's and some of the newer ones with mods. When I get ahold of my bud, I'm gonna get him to raise my TC Lockup mph and that should fix it theoretically

 

if your truck isnt fly by wire, you might have a bad spot in your TPS. Conatacts break down at the position you mostly drive in.

 

Hey, just noticed that you live in San Angelo, I just moved from there. I live in Sweetwater now but am in Angelo on most weekends.

 

I'm glad I'm not the only one with this problem. I'm going to try the brake check and see what happens. Has anybody found a fix for this because it sure is annoying...

 

Cool. I'll keep an eye out for your ride. Mine is a standard Pewter Excab, but has a Earnhardt Sr #3 on the drivers side back window and Jr's #8 on the passengers side.
