What IS Happening to my Car?!
Well, I just now got home after some hard runs, like redlining it a couple times. On my way back, the idle started messing around at traffic lights and droping almost to the point of shutting off. It actually did while i was in a drive through line and all i did was take my foot off the clutch for like less than a second. Also, ive been noticing my brake would drop the idle a couple hundred rpm's. What do I do?!

Your BAC valve sounds messed. It controls the amount of air entering the intake to compensate the engine for the loads that other operations of the car create.

General rule of thumb...never tough the variable resistor. It's set perfectly at the factory. I've never heard of anyone's variable resistor breaking. Unless you took a sledgehammer to it or something. I would recommend checking for leaks. Sounds like maybe a hose cracked or something.

It sucks, but ive never actually had a rock solid idle in the first place. If I have a leak in my vacuum hose and I fix it, is there a possibility my problems will be solved?

the idle mixture, the one down by the pressure sensor that has a big L and R to adjust rischness at idle. like gingenhagen said, dont touch it. the reason i know mine is broken is because it is only supposed to make like 1 1/2 complete turns and mine just continuously turns, it is stuck on lean and i cant richen the mixture to get it to idle.

I have this exact same problem. After a hard run like redlining thru 1st and 2nd my idle will drop down to where it looks like it should die and the shifter shakes. I know that my engine isnt weak I just had a compression test done and it was around 105 on each rotor.

where can you get a BAC filter?
Lordco? what part number would it be?
just to clarify, the BAC is a little vacuum valve that exposes when you take off the stock air box right?
