Indicates faulty brake booster

First thing I'd do is remove idle speed motor, or idle air control, same thing, different names. remove wire connector, remove motor, and get some throttle body spray cleaner, and spray shaft & tip of motor well & clean it all up, as well as spray in to port (hole) that it came out of. Re-install & try that. They are pretty common problem. If it cure it for a while, then starts to act up again, replace it, and clean port well before installing new one. here's a link to give you an idea of what your looking for, click on pictures to expand them.

This is a comon problem with GM cars.Most likely cause is the torqe converter clutch lock up solenoid.

Hello
I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble
