I'm new to the world of boost, so please forgive my ignorance.

I just discovered a missing vacuum line coming off the stock boost control solonoid and can't find where it connects to. I was working on the engine a couple of months ago and apparently forgotto reconnect it, and now is MIA. I believe it's called a signal line. Car idles very rough with surging RPMs, but runs great under power. The solonoid has 2 signal lines and the one missing is located directly under the line from the throttle body.

thanx in advance for any help.
 
I highly doubt anyone here will know, mainly due to the fact that this site is dedicated to dsm's.
 
You lost boy? hehe just kiddn. Get a chiltons manual or a PONTIAC website.
