I use non-chlorinated brake cleaner to clean my TB

 

Thanks to all for the great information here. Wife's been driving Big Red lately and today was the first booger freezing day here in Michigan and had this issue, lightning bolt, 500-1,000 rpm, no power. I'm gonna pull off the throttle body, clean it (2003, 1500 with 5.7l Hemi) with brake cleaner. Since I'll be doing this in probably 0 degree weather, are there any issues I should look out for since all the parts will be very cold, plastic doesn't like cold.
