What sort of shape is your CAS in?

This is usually a symptom of a bad CAS.

You have to remember its 2010 now, these motors and electronics have been through A LOT, if they are original pieces that came with your motor.

Bad CAS is a big issue I have been running into on a lot of peoples cars lately, way way more than it used to be in the past

I fixed my boys car that has a similar setup...
Change the blk/yellow...wire at the f9-f10 connector..
TO TRUE SWITCHED IGNITION
It will garauntee u a steady voltage at ur iacv..
It werks...
