What's up.. I'm running Chrome on a turbo b16 .. it is great, except at idle, sometimes it fluxuates rpm's from between 500 - 1000, or 800-1200... and sometimes it just goes down really low and feels like it's about to stall

Is anyone else having this problem? Any help appreciated!

 

Is it tuned, and do you have a wideband in the car?

 

yes it is tuned .. and the wideband was in the car when my boy tuned it, but it is no longer in the car.. should it be?

 

It's just helpful to see the AF ratio to diagnose things like this. I've found that the motors are more tolerant of rich AF ratios at idle than lean, so a guess would be add fuel in the idle region, but it's just a guess. When the car was tuned, did it idle ok?

 

My guess is this has to do with your "boy" tuning it.

Have him check all the high vacuum (idle) ; low cam ignition tables up to 1200 rpms.
Set them at the same amount i.e. 16.5 deg etc...

Also, play with the idle set screw on the throttle body.
