I had a thread on this a while back but I decided to start with a fresh one...

I just have one question: If the BAC is not hooked up, is it possible for it to be get stuck open? I have had some crazy problems with mine sticking, and i'm blocking it off for now and dealing with the cold idle problems until i can figure something out...

Basically, my BAC gets jammed or something after driving it a little while- whether or not it's plugged in.
