I’m not sure why other perimeters to look at, but I’ve tried my best to look for a vacuum leak on my own. Today while driving, my car stalled randomly and I had P010D and P0507 come in and they would not clear while idling. I know that my PCV system is not hooked up normally, but I don’t understand it enough to know if it’s right or not. Can someone help me narrow down the issue or help direct me where I can start looking for the issue?

Short Term Fuel Trim adding 30% fuel, MAF sensor Voltage High Bank 2, High Idle codes.
What are your o2 sensors reading while driving outside of boost? they should be 14.5-15.5
Start with cleaning the MAF sensors and clearing codes/resetting ECU learning. If the problem still exists you most likely you have a vacuum leak. Start the car. Start spraying brake cleaner on all possible leak points while idling. If idle increases that would a vacuum leak.
If that has no results, perform a boost leak test.
