Bouncing Idle-newbie to the 13b
 

I just recently bought an '87 TII and for the past week or so it's been having some very strange idle problems. When I turn on the car it will idle at around the low to mid 2k range. Then when the car warms up, it will lower to maybe 1700 rpm and then the trouble starts. It will start bouncing around maybe 1600 to 1900 rpm. This car is completely stock, save for the crappy shift stick (I hate that thing). I tried adjusting the idle screw on the BAC valve and it changed nothing. When I let out the clutch out abit, it will stop. It seems like it will run fine off-idle but when idling, it scares me. I have no idea what it could be. I ordered a BAC valve. It seems like that alot of the TII's have idling problems. It would be great if someone could point in the right direction.
