Alright, my car is wanting to idle just a hair too low. There is no BAC on my car (It was removed and the manifold was filled with JB Weld...this was done without me being told...but that's a different story) Anyway, I was under the impression that the best way to adjust your idle was through the BAC. Is there another way to go about raising my idle? Right now the car won't hold idle when cold (to be expected with no BAC), and when it's warmed up it tries to idle, but it is right about 400 rpm, so it stalls alot when I try to let it idle. So, is there another way to up the idle a tad? If so, give me as much detail as to where and how. Thanks.

 

the idle adjust screw on the top of the throttle body. also consult your FSM or www.fc3spro.com and look at TPS adjustment

 

On turbo II's, look behind the intake on the passenger side...under the IC. There will be an 8mm locknut with a small setscrew inside...loosen the locknut and turn the setscrew about 1/2 or 1 turn clockwise. This will raise idle a couple hundred rpm. Continue as needed. Back the adjustment off if the idle gets too high. I usually like to set no-BAC engines to around 900-1100rpm idle, which even allows it to idle on it's own when cold most of the time without a thermowax.

 

found exactly what I needed on fc3spro....awesome
Thanks guys

RR...thanks for the tip on setting the idle a little higher for no BAC cars. I'll definitely do that.

 

I could not get enough out of the idle screw on top of the plenum, so I had to tighten the throttle cable. Are there any other tricks for N/A to get higher idle?

 

The NA adjustment is on top, at the front corner...same as listed above in my post. The NA's usually have some jb weld blob on top of the adjustment, just chip it off with the screwdriver and a hammer.
