alright, when I started my trek from Pensacola, FL, my HEMI started having issues while displaying the throttle position warning light: )Z(. It started around Cheyenne, WY and happened twice more between there and Bozeman, MT. It happened again on my way from here to Seattle, WA to check in and yet again on my way back to Bozeman. Now, just this last weekend, we went to Bridger (just 16 miles away) to go skiing. When we left the mountain, my check engine light came on and wouldn't go away (not with restart or clearing DTC with my Superchips). About half way home, the damned TPS light: )Z( came on again.

When the TPS light comes on, the engine drops to an rpm range which will maintain a 20mph crawl when in gear. As soon as I restart the engine, it will clear (at least untill the next time it happens). I can't read the DTC and the dealerships tell me they can't do anything unless it comes on for them when they drive it.

What the hell is going on with my truck and how do I fix it?

Thanks guys.

But there seems to be a lot of those types of problems going right now!!

Maybe this TSB has something to do with it.

try just cleaning out the throttle body,they get gunked up and in cold weather they get sticky.

Everything seems to fit except the temp and the start-up. The first time it started south of Cheyenne at about 40-50 degrees and at highway speeds after about 6 hours of driving. The same was true the second and third times it happened but after about 3 hours. The fourth was again, the same but after only 2 hours. The last time, yet again, same temp range but after only 10-15 minuets. And it hasn't happened since. Every time, I was traveling at highway speeds. Also, I haven't been traveling that fast since.

Having the same problem with my truck. Happened around 50 degrees cruising down the highway around 70 mph. Anyone figure anything out on this yet?
