[QUOTE="encasedmetal, post: 11792992, member: 80137"] if your car is stalling only at temp but not before it's either one of 2 things or both. 1. as the car gets to temp things expand- especially your throttle blade which most people set the throttle screw before the car is to temp. so once it reaches temp and expands your TB chokes off the car and the IAC valve can't do it's thing. try and log ISC duty cycle, TB absolute and ISC integrator and I'll be able to tell you where to go on that. 2. fueling. for instance- when first tuning my car under cold start conditions- it would idle like hell at 19-20 afr until it warmed up, once at temp it idled right at 14.7-14.8 afr. big difference. so make sure you're logging while at temp and then your maf transfer tables can be scaled correctly. other thoughts from previous posts- never ever put your pcv air before the maf- I saw this earlier in your thread and is a big ****ing no no. pcv will also have dick to do with your vacuum. and plus if your seeing 20# vacuum at idle you do not have vacuum leak. my car sees almost 0 vacuum with my cams and runs like a ****ing champ.
