Turbovert shuts down at stops after A/C recharge

***Searched*** i have a 90 Turbovert that i recently recharged the A/C and it works fine.since the recharge its shuts down a stops and red lights.i have to give it a little gas so it wont shut off on me.
here are mods:
s5 turbo swap
Street Port
HKS BOV
HKS Filter
Aluminum TID
Custom Exhaust
Emissions removed
3000GT fuel Pump
REDOM ECU.

i read in the Haynes manual that i can adjust the idle on the BAC valve,but its blocked off.i was wondering if this was an idle problem,if so where would i adjust it?


Thanks for reading and any input is aprreciated.

compressor is probably kicking on now and your car can't handle the load

ECU and the BAC bump up the idle to compensate for the load when the compressor kicks on.

Without the BAC, your car can't do this. You could compensate somewhat by setting the idle up at 1000 rpm or even higher if necessary.

Funny, our turbovert dies sometimes when you let off the gas too. I'm replacing the dashpot but Ive been told it may not make a difference because we have an Act Streetlite flywheel. They said that the fuel is shut off when you let off the pedal to save gas and doesnt come back on until 1400 rpm. But with the lightweight flywheel the R's drop off too fast and the engine dies. We have a rock-steady 750 idle and a working BAC.

Do you have a lightweight flywheel?

BAC is important, you shouldn't have removed it.

I will be experimenting with a IAC from another vehicle, controlling it with the Wolf.

When we get around to it I post my results. I want the car to act more like a factory car, meaning the idle comes up when its cold, and compensates for load such as when the AC kicks on.

i removed all emissions from our turbo vert and had the same problem,only diference was that we have a large streetport on it,so all i did is put the idle to 1000-1100 rpm.car runs good,when the a/c is activated it drops to about 900.just raise the idle and you should be good.

Why not just shut the A/C off when your stopped? A couple seconds without cold air is better than your car shutting off.
