Stalling/surging when coming to a stop/reverse
Has there ever been a standard resolution to this?? I have searched all over the place and the threads just end with no resolution. My car starts and idles prefectly. wouldn't change a thing but soon as I put it in reverse and start to pull out of the garage it surges and stalls. I bandaided it by changing the throttle cracker enable to 30mph and disable to 29mph. I can back up and drive slowly with out surging but still get it when coming to a stop. What is the correct way to rectify the problem. I will assume once this is resolved that most of the lockup bucking will go away as well. Please help me out.... Thanks...

Sound like you need to increase your Idle Air Table. You'll know when you have too much, it will have a cruise control effect in an auto or the rpms will hang when you let off the gas while moving, M6.

How much should it be increased? A couple 1/10's or multiplied by a percentage? What tables should I be logging? I am pretty new to this so please bear with me.
