Bridgeported FC won't idle
 

I recently bought an FC that was bridgeported and it won't idle. I knew this going into the purchase, I was just wondering if anyone knew how to fix that before I decided to take it to a performance shop. Also, this FC is my first foray into modded vehicles and rotaries. Halp please!

To my knowledge bridge ported motors will idle rough. Is it a big bridge or do you not know?

I was informed that it is a "full bridge". I've been surfing around and found a bunch of people that say their bridgeports idle between 1500-1800, mine just doesn't do it at all. I have to feather the gas whenever I'm not cruising or accelerating.
