MY TAHOE IS OCCASIONALLY STALLING AT IDLE. I LOOKED FOR THE IAC VALVE PER YOUR SITE INSTRUCTIONS. I FOUND THAT MY TAHOE HAS AN ELECTRONIC CONTROLLED THROTTLE AND NO IAC VALVE TO BE SEEN. MY FRIENDS SAME YEAR TAHOE HAS THE TRADITIONAL THROTTLE BODY AND IAC VALVE. SO I WAS ABLE TO COMPARE AND SEE THE DIFF. DOES MY TAHOE HAVE AN IAC VALVE, AND WHERE? IF NOT, WHAT DO YOU RECOMMEND. THANKS, ROBERT.
