i dont have a screw to adjust my idle via BAC... i car has a little miss at idle (some of you downloaded the video) and i think if i adjust the BAC and get the TPS set right, it will idle fine...
do i need to get a new BAC since mine doesnt have a screw in it? also, are the turboII and NA BAC's the same part?

 

dude, i hope you figure it out, ,cause i never had ANY luck trying to set the idle with my BAC untill i switched to a haltech..

 

Turbo bac have a screw. Non turbo don't. You should have had one. Sounds like someone switched one on you.

 

hmmm, think that could be my idle problem?

Fully warm up the car. Pull the bac plug off. Any difference??

Or......just install the initial set coupler. Any difference?

American or Jap engine?

 

jspec S5 TII engine. i was told the japs didnt have a screw on their S5 TII BAC's.

i pulled the BAC plug while idling, idle changed. now what?

 

what does bac stand for?

 

It means the bac is working and trying to keep the idle around 750. I think you need to find a bac with the screw. That is the only idle adjustment on a turboii....unless you had a 87-88 then you could use their variable resistor to help out.

Seems the throttle stop screw is your best bet. Small screw with a 8mm wrench size jamnut on it. Ont the aft side of the throttle body.

B A C bypass air control

 

i got it to idle around 800-900 or so and hold it somewhat smoothly, but its just not SMOOTH. it sounds like my motor is ported or something. damn japs

 

That remark is totally uncalled for.

 

yep... unless your japanese of course

 

I can't think of anything else since it's a series five. Except maybe a SAFC (more money in the money pit).

Maybe the timing is a bit too far advanced???

Yes, Damn Japs. Remember Nanking, Bataan, Manila, comfort girls from Korea and list goes on and on.http://www.cnd.org/njmassacre/recent-news2.html

 

LOL hailers you weirdo.

also, i have an SAFC.

 

Hey Skunk,
As you know since you're in Hawaii, that sort of remark will get you beat up and thrown over the bridge.
I cringe everytime I hear the word "Jap". I know people don't mean it as a deragatory remark but it is.
