No sir. But here's what has happened since changing the plugs 9/22. Ran from 9/22 to 10/1 without issue. This included a 6 hour drive from east TX to the hill country on Friday night. On the return trip home on Sunday, the first 45 mins were uneventful. In the 30 mins following, the truck went into this "limp" mode 4 different times - always in 6th gear. Same fix every time - coast to a safe spot to pull over, stop the truck, put it in park (running rough as heck), turn it off, turn it back on and go. I disabled 6th gear. Cruising at 70 seemed fine in 5th gear until I hit a steep grade in cruise control - when it downshifted to 4th gear it went into limp mode again. All of this happened in a 30 mile span. So my next run at this I disabled 6th gear again and didn't use cruise control and made it home fine. It did finally throw some sort of code I assume because a check engine light came on and stayed on. It's at the shop now. Will advise.
