bad hesitation at 1/2-WOT... HALP!

My car was fine before I installed my FMIC for the most part. In neutral or while driving the car it stumbles when i stab the throttle then regains power and is fine. The car does not continue to buck or hesitate. Just once when i hit it. This is what changed after the fmic install:

Obviously the fmic.

BAC hose that originally went to the tmic goes no where and is not blocked.

I had to remove the lower front throttle plates because my dashpot thingamuhjig was stuck.

Car idles fine. any help would be great.

I hear that the removal of the throttle plates may cause a hesitation on the low end. Do a search on that.

Also, that line needs to be either blocked or re-routed onto the fmic's piping. I would re-route it because the BAC is pretty useful if you still have ac/ps.

BTW: I love my Intrax springs and if you ever want help on your car I live in Taunton. Try to make some meets sometime! Stop working so hard!

BAC definately needs to be plugged, blocked off, or reattached. whe it kicks on you get a vacuum leak.
