DodgeForum.com - Electronic Throttle Control Question?

I have been having some problems with my truck these past few days. It has been very cold lately (down to -10, -15 with a -30 windchill). I don't know if this could be causing the problem, but it just started happening these past few cold days. Anyway, I was coming home yesterday, the highway had just been plowed of snow, but the regular roads where still full of snow leaving a drift between me and the highway about 2 foot. I hit the drift at around 10 mph, not to hard, and was off on my way home. I came to the side of the street where I normally park and when i hit the brakes to stop my truck shut off and said check gauges. I was not really looking at the cluster at the time, so I figured it must have just had a glitch or something in the computer so I locked it up and went to sleep. This morning I come out to start it, started fine, went back inside and let it warm up for about 10 min. I came out to a diesel like noise, I looked around and did not see any vehicles around so I went to my truck to check and sure enough it was that. Really rough idle almost like it was misfiring. I went into the truck to turn it off and I seen the Electronic throttle control light blinking (at the time I didn't know what it was) so I turned it off and ended up calling in for work. I have done a little searching on here and havent really came up with a strong idea what is wrong. My truck is a 2008 Dodge Ram 1500 SLT BigHorn with the 5.7L hemi and just of 36,000 miles. I did the the code check on the odometer and nothing showed up. Any idea what this could be with the events that had happened
