This afternoon at work, I was leaving the firehouse to go to a school to teach, had just driven in to work and turned off my truck for a couple minutes (so engine was at temp and driving fine prior). Got in my truck, and as I pulled onto the main road I opened her up a little bit. Promply the truck shook, revs when high then low then high again, "check gauges" light was on and the etc light was on. Turned off truck and waited a minute. Turned back on and all was fine, no check engine lights ever turned on. I drove around for a bit, and there were several incidences, every 10 -15 minutes or so, of a stutter or something like that while driving, especially after getting on it a bit. Checked all my fuses, checked for codes with a reader, none found. Plugs have 2-3000 miles on them, same as wires. Nothing obviously messed up. Any help would be greatly appreaciated.

 

Gonna be a bi*ch even for a dealer to diagnose without a CEL, but my first guess would be TPS.
Try a TPS reset (search on here for how, it's usually discussed once a month or so) and see what that does first before spending the $ on a now sensor on a guess...

 

Actually that was the first thing that I tried and it seemed like it helped but didn't cure.... IDK
