So my car has idled like *** for a long time and someone told me to adjust the screw that sets the idle (on the BAC valve). So I looked up in my Haynes manual how to do it (cause I"m a moron and figured there'd be somethign else then just screwing in a screw). As you can imagine, it told me I had to connect my initial set connector. So I did that annnnnnnnnnnnndddddddddddddddddd...... car dies..... Go restart it and connect it again, dies..... It died every time I connected them.... Sooooo what does this mean? Thanks!!!

BTW I have a 1987 TII

 

From what I understand the initial set connector disables all electrical functions that help keep maintain idle. If this is correct that means the only reason why your car is idling is because one or more of your electrical components helping the idle is doing alot of the work when it shouldnt be. It should idle with the initial set connector. This is all from memory so dont sue me if I'm wrong. Not sure if I phrased everything correctly but I think you get the idea.

 

No, it should not kill the car. If it does, check your BAC valve. It likely needs to be cleaned.

DO NOT adjust ANYTHING until you can verify that your TPS and BAC valve are working properly. Also, fix all vacuum leaks. Idle adjustments don't just suddenly go wrong. It's likely something else.

 

It sounds like the BAC valve is not working properly or your sensors are adjusted way out of spec.
The initial set coupler primarily shuts off the BAC valve so you have zero idle compensation when adjusting sensors.
