Stalling 2000 caravan

[chevy21057]

I have a 2000 flex fuel caravan that just started dieng at idle. It has been about 10 degrees the past 2 days and are van doesnt want to idle after it warms up. If you keep your foot on the throtle it stays running but if you take it off it dies. I put heet and lucas fuel treatmant in this smorning but it still is doing it . I am guessing either tps or temp sensor any help would be great.

Temp sensor is likely to cause problems only when it is cold out, I would expect the TPS to not be temperature sensitive.

Thanks it ended up being the iac. I cleaned it up and now works great. Thanks for the help.

i had a problem with my EGR valve and solenoid i never got a check engine light but it would die under 1k rpm till it got hot.dont know but this may be part of the problem.
