Hello all, car is still doing fine, except that I have a really annoying problem, the idle keeps going up real high. When I crank up the car, it will idle at 900 rpms, where I want it, but when I start driving, let it warm up, when I come to a stop sign, the idle stays around 1100 - 2000 rpms, to get it to come back down, I have to blip the throttle a little. Would this be my air pressure regulator?

It's your bcdd (Boost Control Deacceleration Device). The device is located Halfway back on the bottom of the intake. This device slowly brings the rpms down when you deaccelerate or when you shift. There is a nut or screw (depending on year) at the bottom of the device. You will need to turn the screw/nut to adjust it.

hope this helps you out.
