bac Valve
I have a 87 TII.
my car has a really rough idle problem,
I try to adjust the idle screw on the BAC valve, but it doesn't make any differents,
and I unplugged the electric connector on the BAC valve , but it doesn't make any different too. so I took the BAC out and clean it , and it still doesn't work. is that mean I have a bad BAC? my problem is can I use 89-91 BAC valve on my engine?
will exhaust leak cause bad idle?
PS: TPS is good , and engine has good compression.

Had the same problem. I was getting funky idle problems and adjusting the BAC screw didn't seem to do anything. I bought a used BAC off a friend and replaced it. It seemed to do the trick. I have an 87 TII also.
