Hello everyone,
I'm looking for some advice on how to resolve the idle hunting that I'm experiencing on my cammed M6 ls1 C5 vette. When I come to a stop with the gear shifter in neutral the rpms will sometimes drop to 400 then raise to commanded 850 and back down again before it settles . I also notice that the AFR drops down to low 12's as well. The car was tuned by a local tuner that is no longer around and I'm pretty satisfied with the cruising and PE portions of the tune. I currently have a friends Flashscan V2 and have been familiarizing myself with it's functions. Can someone please offer some tips? Is it spark related perhaps? Please see list of mods and current tune below. Thanks a bunch! -Josh
