Erratic idle.

Okay, I'm at a loss. My 09 DCSB v6 started dying at stop lights today. Cleaned my MAF last week because I was getting like 3.6 g/s of air at idle and should have been been around 4.2. I have an AFE cold air intake and found out last week that the gasket where the maf connects into the intake tube was pinched. I do not have a CEL on and no access to a bi directional scan tool right now. Anybody know if the 1gr has an IAC? That's my next step

 

2009 is a second gen. You posted in the first gen area.

 

You have electronic controlled throttle. If the plate is dirty after a battery is disconnected it will idle super low due to needing to learn the new "dirty" position of the plate.

Take off the intake ducting and clean the throttle with intake cleaner or penetrating fluid.
