I think I may have mentioned that I developed an idle surge. I initially had the screw in the top of the TB backed all the way out after the emissions removal and it held around 900RPM.

Lately its been idling around 1500 and surging to 2000 intermittently. So I was reading on the other forum about it and found one thing that said adjust the screw so I screwed it all the way down and it brought it back to around 900-1000. After I started driving it the idle jumped back up to 1500 but didn't surge any more and then settled back down to 900. Still no surge so thats good.

Do you think by BAC could be bad? I know i dont "need" it but it does help with idle speed. I suppose I could unplug it and see how the car responds.
