Hi guys! Have you guys dealt with a lean at idle bank 2 code before? What could it possibly be? Most likely a vacuum leak after the maf?

 

Sounds like a good place to start. You also might want to try cleaning the MAF's.

Also, possibly check to make sure your fuel pressure regulator line didn’t pop off. Here’s a good thread on that below. Also can cause a lean condition.

It is recommended to read the fault code via an OBD-II diagnostic device and further troubleshoot it in conjunction with engine data streams (such as fuel correction values, oxygen sensor readings, MAF sensor data, etc)
