My car has been idling poorly since I started it up, and after adjusting the throttle stop, it hasnt helped much, the engine is very shaky. I removed the following:

BAC
ACV
TB Mod and removed thermowax
OMP
vacuum rack
Twin Scroll
EGR
Start Assist
AWS

Is there anything i can do besides reinstall the BAC?

 

You should be able to get a high enough idle speed without the BAC valve, you just get very poor idle control (there's a difference). Look for vac leaks.

 

if there is no vac leaks there are 3 things to look for.

TPS
Idle mixture (via pot)
Butterflies

also make sure you have your injector air bleeder hooked up properly.

set the tps before moving the butterflies.

 

yeah the injector air bleed vital to a stable idle. sounds like you did a full emisions removal, so you have to make ure to reroute them from the nipples on the back of the TB.
