IAC Valve
Did not fit tight. The screws that came with it were not the same, causing damage to my Intake manifold. Try to place old screws back on and thread was gone.

No more stalling
This valve took care of the stalling that was happening when the engine was first started, before it warmed up. Replacing this took care of it. Engine starts and runs good now.
