Hey moolan, I ahve the same problem. do you have cams. The only way to raise the idle is to have a custom chip burned with a higher idle. I just had mine re-done to 1000epm. It helps a lot. If you need more info, call me

You can physically raise the idle adjustment screw but it will make your car run weird. Since the idle is computer controlled, if you raise you r idle to 1100rpm via the TB then the computer is fighting the TB settings.

The result, rpms hang when shifting(I mean like for 5 seconds) and the car takes forever to get back off of idle. There is a fine line of adjustment. Try it and you will see what I mean. Just by the chip, it's only 195 bux and is worth it for the little that it does.
