Help! - no idle when warm!

[Ameer Antar]

Seconded, TB cleaner is the way to go. Other than that, you may want to
double check the idle temp sensor. It's dedicated to the idle control
system. I think it's the red one that faces up on top of the coolant elbow
near the valve cover. Also you might want to swap out the Idle control unit
under the dash. Used is the only way to go, but sometimes these get
corrosion or loose connections in them. Just removing and plugging in the
unit will move the wires and possibly bring things back into operation.

good luck.
