Slight idle/rolling surge
Hello all, 1st post here
New to the tuning game and been reading around on here to gather as much knowledge and info as I can. Reason I come to you guys today is that I am trying to track down and eliminate a small idle surge issue.
Little rundown, back in fall of last year I upgraded my cam from the previous small cam to another "smaller slightly larger" cam. Everything went great and ran awesome for a small cam car. Fast forward to around 1st of the year and started having some issues, fought and fought with tuning and inspecting things to finally find out basically had blown both head gaskets. So now that everything is back together and running, I am having an issue with the idle and best way to describe it is that at idle only when car is 1st started and warming up, the rpm's will climb to around 1200 to 1300 rpm when clutch is pushed in during a rolling stop. Also it will idle great and not fluctuate at all when good and warm, until the a/c or heat is actually running, then it will surge, but only when clutch is pushed in and car is moving, then it will idle good when car has come to complete stop. Any idea's what to look for to possibly adjust/correct these slight issues? Current cam specs are 226/232 .58*/.57* 112lsa. Basic bolt on modded 2010 SS w/ 2in LTH and no cats. Hand port/polished heads. Attached couple of logs and tune files. I hope it works.
Thanks in advance
