Fast idle valve or idle air controll causes that ..BUT it can also be air in your coolant ..coolant travels into the fast idle and idle air control ..bleed out the air try turning down your idle screw alittle bit is that doesnt work..if not pull off the upper charge pipe and let the car idle ..look inside the throttle body and you will see 2 holes ..these are the air passage for the idle air and the bottom is for fast idle. if the fast idle is sucking air after the car is warm thats your problem..

Re: (GSRT37)
To check this problem, take off your upper charge pipe from the throttle body, if you have a huge vacuum leak you'll hear it, and there is a hole in the outter part of your throttle body, if you putt your finger over it and the idle goes back to normal, it is surely your fast idle valve.Ta ke out your fast idle valve below the throttle body, there is a plastic cap that threads in, it will probably be loose. just thread it back in and you should be fine. Good luck
