L76 idle hunting while warm

[demonoffroad]

Good Afternoon Evyerone,

Like many I am a rookie tuner here, but would like to think I have a pretty good understanding of how it all works. Just completed my camswap/DOD delete on my '08 Pontiac G8 (L76). Went with a 225/236 113LSA camshaft. Car has a Vararam Intake, Pacesetter long tubes, no cats, Magnaflow 2.5" header backs. No other mods for now. I got my base idle tune semi dialed in in a rather conservative form and have a good quality idle that is right on the money. HOWEVER, i'm having problems with 1. Random misfires showing across all cylinders. You can't really feel them, but i believe it may be the reason behind my odd exhaust flutter. 2. When warm it has a tendency to idle hunt when you start it up. It will do this until I manually blip the throttle and then it will settle back down to desired. I tried searching around a bit, but didn't find much that was of good use. Any help would be great!!
