l99 but deleted vvt,afm,dod running on 91 with meth. installed btr stage2 turbo cam,runs flawless above 1400rpm but cannot get it to idle properly.replaced all vac lines no leaks but will only get to like 80kpa at idle so no brakes and REAL choppy attaching the tune from after the dyno just looking for any help with the idle, and no i did not tune but trying to fix so i dont have to deal with them anymore.can get a log if needed but spark bounces from like 9-20 in park and drive with brake on
