I have a turbo obd1 B16 and my car is not wanting to idle all the time. It will idle when its cold sometimes, other times it will just die. Same when its warming up and even when its warmed up. I have no idea what it is... Sometimes it will idle really well.

I have a VAFC2 and chipped P28 on a street tune, I was thinking about trying to adjust it using the VAFC2 anyone have any ideas on how.

Any ideas are aprecciated.

 

Well is the car REALLY street tuned, meaning part throttle and air fuels are good, along with timing and everything, or do you just have some bullshit "basemap" on there. If it's tuned then you can try a couple options, if it isn't then obviously you jus need to go get the thing tuned.

Check your idle air control, they have a screen on them that get clogged occasionally, and if there is a check eng. light on check it out. You can check you idle screw on the throttle body too. Turn it all the way in, then back it out about 1 full turn, and a half turn. After that start the car and adjust from there till you get where you want to be.

If all else fails, there is a very small allen key UNDER the throttle lever. It acts as a bump stop for the throttle. You can adjust that so that it sticks up hitting the lever, and that will leave it cracked open @ idle. That will DEF. raise the idle, but i always use that as a last resort. Make sure the car is tuned before you pick your brains, that very well could be the whole issue.....

 

Yeah, its actually street tuned. I just adjusted the throttle cable to crack it open so I could make it home. Wasn't idling with headlights/turn signal/fan/heat/stereo.

I am going to screw with it tomorrow, thanks for the ideas! Any more would be appreciated, I heard something about the BOV causing idle issues, is it drawing to much vacuum at idle?
