So I got a check engine light on my supercharged 2008 Avalanche this week. The code reader says it is a P0174 fuel system lean code. Here is he report.

Upon some research this code basically points to a vacuum leak or could also be an exhaust issue. (bad back pressure ). The shop that did my blower says they often see this when cats go bad.
Upon inspection i found this:
I jiggered with it a bit and the code went away. I'm going to get a second opinion but this cracked hose is my top suspect.
Any insights are appreciated. I'm mostly documenting this for reference.
