Got an '02 Camaro with bored 6.0L (to 410), FAST heads, 102mm TB, mild cam (232/227 or something close to that, 580 lift), long tube headers. This thing will simply not idle right. Even with those mods, I should be able to get a rough self-sustaining idle with stock idle tables.
I've read and tried just about every sticky and suggestion here, and am about to declare a mechanical issue is at fault. I've attached a log. Of interest is the first 10 seconds or so, then the part after the long 2000RPM run. This was run using the sticky that Bill posted here.
Sorry, no AFR because it's too erratic to register on my dog-slow LM-1.
