I'm experiencing a random idle surge on my '98 LS1 Camaro. I last got a tune back in 2005 or so, but since that time, the idle has gotten progressively worse. It's not horrible, just annoying. Every once in a while, while driving, the car will die when coming to a stop with the AC on. I've replaced the O2s which improved the idle a bit, but not enough to completely eliminate the surge. I rarely drive this car, so I've put it on the back burner until now and finally just got tired of dealing with it.
Mods are heads/cam/FAST90/full exhaust/4600 stall. Cam is a 230/234 .600/.600 111 LSA with 110 ICL (nothing too radical).
I'm going to post my tune and a log of the surge. Let me know if anything seems out of the ordinary. Also, this is the first time I've posted a log so I hope it works!
