I recently did a FMIC in my TII and directly afterwards, I started having these nutty throttle problems. If I keep it out of boost, the car drives fine, the second I go full throttle and let off for a sec, the revs spike all the way out. I checked for intake leaks and such, replaced the throttle cable and lubed up the linkage at the TB. Any other ideas?

I did have a coupler pop off on me at one point but that didn't really seem to fix the problem either.

The car is on a Microtech LT-8 btw...just to eliminate and ideas for the stock setup.

how much boost you pushing?

10-12 psi

your pretty close to me. i would say you either forgot to connect something or have a loose coupler somewhere

maybe. I'll run through the couplers again... I'm damn sure everything is connected where they should be though. I quadruple checked it.

Couplers are fine, throttle cable is fine, no vaccum leaks...tb linkage seems fine too.

I'm absolutely stumped.

The last thing is physically pulling the TB and checking to see if there's anything gumming up the plates. It still doesn't make sense because it doesn't stick until I give it some boost...
