also want to know the same thing, my g6 is over fueling badly boost is down, pulling timing and has a rough idle sometimes.

There's a hole on the right side of the circular part of the PCV. Check if it's blowing through, block it with a finger and observe

Try this. Unplug the maf sensor plug.

Does it idle smooth?

took the car to vag motorsport, they ran some tests and boost tested the car, turns out that the air intake manifold is cracked, hence the boost leak and running lean
