Engine Dies at Idle

I'm trying to figure out what is wrong with my Sonic.

The check engine light recently popped and I noticed that the engine dies at idle if not warm up.

It's all stock minus the DDMWorks Cold Air Intake.

I went to AutoZone to check the codes and like 13 popped out. They said the engine is running rich, the turbo is underboosted, not enough air coming in.

So I'm guessing is this from a vacuum leak? Could this be because of the air intake?

You only recently put it on and started having the problems? An easy way to find out would be to put your stock air box back in and see if the problem goes away.

I put it on three months ago. I was also told that it could've taken a while for the computer to catch up with the new air intake.

I'm going to swap it out & troubleshoot it.

One time my engine died while in neutral going down a giant mountain. It's not like your issue, just kinda sharing.
