Hey guys, i've been having some trouble with my RPM at idle, and while driving. If I'm idling, then rev my engine hard, as the RPMs come down, it falls to about 300, then stalls out. i have to feather the gas to keep it running, then it will return to where is likes to be (1000 RPM is my case).
it does the same thing when I'm driving.

Is there any setting i can adjust to help stop this?

Thanks.

are you getting reversion? this is reverse airflow through the MAF on deceleration... usual fix for this is a BOV

if you log when the problem happens you normally see the MAF and injector time spike on decel

Im having the same issue with a KA-T setup (no BOV) and sometimes it dies. We are using a blowthru MAF setup, so im not sure if thats got anything to do with it...

I see the AFR's go pretty lean when it happens, still looking into the issue. We checked the MAF and injector time, and I didnt see any spikes upon decel. Ill let you know if I find anything.
