As I stated in my original post I did a search, but there just wasn't enough detailed info. I thought the hole inside the throttle body was supposed to be sucking air. You put your finger over the hole while the car is at idle speed and if it causes a drop in idle everything is OK with the IACV. If i am wrong let me know, I have owned 4 different 5th gen ludes, but I have never messed with one this new. Is the part your talking about called the Fast Idle Thermo Valve if so isn't it only on A/T cars, this is a M/T. Thank again.
