Default SES AFTER CAM INSTALL SOME Q's

I installed a comp cam, with the comp dual valve springs and a set of stock LS6 heads (have the longer valve stems) and Comps 7.4 hardened push rods.
The car has two problems at idle it shows missfires in ALL 8 cylinders and will set the ses light, it does clear up above 1300 rpm's the second thing is while driving like 5th or 6th gear i get a surge/miss every so often and it does show on the missfire graph but doesnt seem to be any one cylinder. I did do a search but none that i found mentioned all cylinders at idle only one or two? Any help is greatly appriciated.

I have a hotcam, and I get all cylinders at idle (peculiarly less on #5 though...). If you are in 5th or 6th I am assuming you are cruising at between 1.5k and 2k rpms? You more than likely need to adjust the set screw on your throttlebody within an acceptable range, like I described in a post near the top of the board (for now). That might be what you need to fix it. Are you using a MAFT?
