Hey guys, need help with a idle problem in a 2004 GTO. It happens everytime you come to a stoplight about 15 seconds after you stop. The car will idle fine and the 15 seconds later it will stumble to about 300rpm and then struggle to pick back up and then idle at it's target rpm just fine. When it does this it only happens once per stop. It seems to me like the throttle follower but i didn't work on this tune so i really don't understand why some things are the way they are. Anyway can someone please take a look at the tune for me and maybe point me in the right direction.
Thanks,
-Dennis
