    i was just wondering if anyone could just look over my idle log and give me a good idea or a place to start on why my idle keeps surging up and down but 500 rpms. no boost leaks up to 15 pounds and only plan on running 12 for now so i dont blow it up. its got a hy 35 speed density, on ecmlink v3. all new sensors on the intake manifold. it idles around 14.7-15.3 at 950 rpms but than leans out to 16-17 even 18 sometimes than raises it idle than goes to 12 and so on. any idea or suggestions would be greatly appreciated im gonna post the most recent log i have of it but it doesnt only after driving not really first start up idling if that makes sense LOL. but im gonna log to work and see if i can get a new log of it doing it!.

    It only does it random or when it been idling for like longer than 5 minutes than it develop it and when I watch the log the time it raises in idle when the 02 sensors are cycling
