The instructions say 4 M6 bolts but the package has 2 bolts longer than the other 2. Where do i position the 4? After install of the 92 combo, my throttle is way too high, I thought the position of these may effect the throttle?

that or you have an intake or vacum leak somewhere.

Has anyone installed the FAST 92 T/B? How do you know where to position the 4 bolts? 2 are longer than the other.

I've only got 4 bolts connecting my TB to the intake. I didn't have any left over that I can think of but not having the top center bolt might explain the high idle and loud suction of air at start up. Is the top center bolt the same as the other 4? I just don't have it.

I believe its the same lenght as the 2 bottom bolts.just go to any hardware store and grab a stainless steel one with a nut behind it.

Hey guys, I dropped my car off at Automotion in Louisville this morning to get a re-tune done after the 92/92 combo install. I told and showed him my issue with the loud suction of air for the first 30 seconds and the idle being all out of whack. For whatever reason, I never considered the source of the problem to be the throttle cable bracket!! An hour or so after I dropped it off, Charles from Automotion called to say he found that the throttle cable bracket was causing the cable to have too much tension on it causing it to keep the throttle body open just enough to create the suction, after the initial 30 seconds, the Idle Control Sensor learned the system and would adjust itself to control the vacuum!! It makes sense to me but I just never considered looking at the bracket, he drilled it out a little bit and lessened the slack on it and it cleared right up!!!!
