How To Adjust The Idle Set Screw?

[lorenambrose]

Can someone tell me the correct way to adjust the idle set screw on a 2003 3.0l Flex Fuel engine?

Lets just say mine was "adjusted" incorrectly and I need to get it back to the proper factory setting.

there is a screw that adjusts the closed position of the throttle plate. It is on the throttle cable bellcrank.

That is a stop.. It is there to keep the butterfly from slamming shut and damaging itself. That screw should be adjusted EXACTLY to where the butterfly is closed but not tearing itself up when the pedal is released quickly.

Yeah big jim nailed it, it says right under the hood the idle speed is controlled electronically and cannot be adjusted.
