Hi, Guys. I am wondering if any of you have had this problem, and if so, how was it fixed. When I stop at a red light or stop sign when it is cold out, and put my foot on the brake, my truck idles at around 700RPM’s and is tight and smooth in its idle, but when it is warm outside, and I come to a stop my truck idles very rough right at 500RPM’s, and it vibrates like it is about to die, but never does. Any ideas? [align=left] [/align]

 

Im not to sure but there has to be a way to raise your RPM , Mine does that too from 700cold to about 600warm or less but no shake, im guessing its the 500 just way to low.But someone else has to let you know how to fix this , i have no idea .
