I am unable to get the rpm's up enough at idle with the engine in drive and the a/c on or off. I have tried to adjust the screw on the passenger side of the intake plenum, it will not turn in any more clockwise. thanks ED

counterclockwise (or loosening) should raise your idle. it sounds like you have the adjustment as low as it will go right now.

 

wow I will try that, thanks so much for your help. Ed amazing it is even staying idleing at all at that setting.
