Ever since my cars rebuild, it has never really idled right on cold starts. It was always a little bit choppy at about 800 rpm with a target idle of 1000. I would expect it to idle high on a cold start but it doesn't. Just a few days ago I put on an AEM fuel rail and it seemed to agitate the issue. Now it wont stay running hardly at all on a cold start and I have to keep my foot on the throttle to keep it running. If I drive the car it misfires extremely bad and sounds like a Subaru until it gets close to op temp and even then feels sluggish in the lower rpm. The only thing i noticed when i looked over the log is that my O2 seems to be reading lean in open loop, and then right when it went to closed loop, the idle shot up to 2k and then the O2 voltage dropped way low and the car started idling horribly again. unfortunately I do not have a wide band though. Can someone please look over the log for me and see if anything looks messed up? I don't want to do anything to hurt the new motor. Thanks
