bac block off plate idle adjust?
your post makes no sense. You can't adjust the idle from the BAC area if it's blocked off. If you need to adjust your idle with out the BAC valve on than you will probably need to use the throttle stop and the variable resistor.
If you've removed the BAC and replaced it with block off plate, then you will have to adjust your idle with the primary butterfly stop screw. You will have the throttle body off a time or 2 before you get the idle just right.
Why did you need to remove the BAC anyhow? I hear they work quite well

Note that it would be better to replace the BAC and all other emissions components if you have the funds, but if not, just spend $35 on block off plates and say "F" it...
They do, but when they go bad, it can cause the car to idle like an angry prostitute... Lol... I removed my BAC along w/ everything else included in the Banzai kit... I only needed to use the screw on top of the TB to adjust my idle... My car usually idles between 850-900rpm now... Your car shouldnt be idling too high... Be sure to check for vacuum leaks...

I'm sure a search will turn this up. Someone has a write-up on using PVC tubing and elbows. That will let you keep a vacuum between the turbo and TB so that you can adjust the idle. I picked up the parts to put one together and lost out to assumption. I ASSUMED by eye-balling that I'd need 2" PVC. Got everything home and found that 1.5" is closer to what I needed. I haven't had time to get back to it, but hopefully this weekend I can.

The BAC valve is pretty reliable. Instead of removing it, troubleshoot the vacuum leak causing it to go crazy or simply replace the valve with another. They are cheap because people always remove them for some reason.
Seems like 90% of cars with BAC valves removed have idle issues. This isn't a coincidence.
