Is there any way to manuely adjust the idle speed. My car is idling at 950rpm and I would like it to be down around 750.

 

ya you have to...while the car is running...undo the idle air bypass plug. the car will either putt out or it may rev to a high rpm. while this is disconnected set the idle with the gold colored screw on the front of the tb. tur turn the screw clockwise to lower...oposite to raise. when your done reconnect the idle air bypass plug and your set.

 

Might be a good Idea to Clean the throttle body(with approved cleaner) and the IAC motor...first...

 

is it a screw in the linkage itself?

 

its on the front right...your left...of the tb right next to where the hose connects.
