Hey guys. So ive been having some real trouble with idle surge over the past month or 2. I followed terrys idle surge guide to a T and still had found nothing so I post this in hopes it may help someone... I had tried everything except a full fiav block off. IAC, TPS, wiring, etc... So finally i sent my throttle body off to throttlebodies.com to be rebuilt to remove any doubt of a bad fiav or plate or what have you... Well after it got back to me I was still having the exact same issues. Hell i even tried switching to speed density to see if it had an effect and it did not. So after another month of trying everything 20 more times i finally said screw it and popped the freeze plug off the back of the throttle body. I saw nothing out of the norm at first but when i rotated the black plastic screw in it began to separate at the middle... My fiav valve had cracked down the center perfectly. It was so fine a crack i cant blame the builder for missing it. But just be aware that this may be the issue plaguing you if you have tried everything but replacing a fiav. Also a warning to others that if you send your throttle body out to be rebuild your builder(or even you) will probably miss this.
