i hear a sucking sound for 30 sec or more when its cold it stops then i can drive off. when i stop at a light the RPMs raise up like im about to take off. sometimes it ideal down.

no. it just does it in the morning when i first crank up and when it sit for a while, and i crank up again only for the first 30 sec
CHECK INTAKE TUBE CLOSELY FOR SPLIT OR HOLE, MAY NEED TO REMOVE
FOR INSPECTION. IF YOU REMOVED THIS TUBE AND STARTED THE CAR, IT
WOULD SOUND JUST LIKE YOU DESCRIBED. THAT'S THE REASON I SAY CHECK
IT BEND IT LOOK ALL OVER IT. WHEN FIRST STARTED THE IAC IS OPENED UP MORE
AS ENGINE RUNS A FEW SECONDS IAC CLOSES AND "SUCKING" SOUND SUBSIDES.
ALSO CHECK FOR LOOSE AIR FILTER COVER.
