Will not idle after warm up.

What is your question?

Engine is 3.8, runs great even after warm up, but want idle. Idle control motor has been changed, along with mass air flow sensor. Throttle body has been taken off and cleaned. It has plenty of power, it just want idle. After warm up the engine will start to lope then dies.

What makes this problem better or worse?

Runs great when cold,
