Help with idle please

[91-gsx]

Hi,

I still have the old version of Dsmlink, so I understand if many of you cannot view the data log. I will try to get a new log with the new version soon.

I am trying to get my idle dialed in for smog. I cannot seem to get it down to 750-800rpm. The fuel trims do not indicate a vacuum leak. I also used some carb cleaner to check for vacuum leaks, but the idle did not change at all. The gm/rev is also low at 20-22gm/rev. I tried adjusting the idle, but even with the idle adjustment screw in all the way, the idle still stays above 1,000rpm.

As a side note, everything was done with the proper idle adjustment procedure. Please let me know if anything sticks out to any of you Dsmlink gurus.

Thanks for your time, and help.
Tony

might be your idle speed motor not going back to its position.

Thank you for the help Lou98GSX, I will definitely log that and make sure if it is functioning correctly. It is a new ISC valve, but you never know.
