Cold weather idle issue

Hey guys, so I just got back from being out of town for a few days and had this issue pop up. It was 50 degrees when I left and while i was gone it snowed and dropped down to 20. Now my car will start up and idle normal but as soon as I star driving and come to a stop, it will continue to idle at 2,000rpm until I restart the car. Also won't boost past waste gate pressure(12psi or so). Im scratching my head here so any suggestions are welcome. Running Cobb stage 3 btw. Thanks in advance!!

Did some logging and it looks like my MAF is dead, was reading 0v. Got another one on the way so hopefully that takes care of the problem.

Sounds like she's going into limp mode. Check for boost leaks and also make sure your FPR hose didn't pop off. The hose I'd over by you power steering pump going to the intake from the fuel rail. If not it could just be your tune if your not protuned.

It was indeed the MAF, those bastards are notorious on our cars for going out. Popped the new one in there and it was good as new. Now, onto this wheel bearing that seems to be going out...
