P0174
My SES light went off today. Luckily I was right by an autozone so I stopped in and the scanner read P0174 lean bank 2. I can hear a really loud airy noise so I assume it is a vacuum leak. I did spray some carb cleaner around the drivers side of the intake manifold around the brake booster hose area and it did raise rpms a little. Although the brake booster line is definitely on and secure. What other lines are around that area that could cause this? Also I'm confused why only bank 2? and not both?

well i found the tube that is broken it is right in front of where the brake booster line connects to the intake manifold. Its a small rubber hose 90 degree angle about 4 inches in length and it busted right along the bend. So how would I go getting a new one of these?
