its your idle control valve. theres a thing under the throttle body, held on by maybe 3 bolts. take it off, then take the 2 screws hold on the plate in the back. unscrew the thing in the middle, clean the tube out, and screw the thing back in tightly. hook everything back up, and see if that fixes the prob.
