BBK Throttle Body/Idle Problem

[trickstang94]

Ive been having idling problems. With my mods my idle sits at about 680, but my BBK 75 mm TB will not adjust my idle up. Sometimes the idle will drop to far and my car will stall. Also after I stomp on it and slow down to a stop my car tends to stall. Has anyone had this problem. Is it the throttle body size(to big?) or is it something else?

Your Idle Air Bypass (IAB) is what takes care of your idle. Not the TB. The TB is completely shut at idle and the IAB opens a valve to let a certain amount of air go pask the TB butterfly. I have a 75mm and no idling problems. Is your IAB hooked up? Do a self-test and see if the computer gives you any codes.

Problem is not the throttle body however I do think its a little big.
