hey guys, 07 yukon running rough here lately, looked under hood and the pcv valve hose is cracked, should i change the valve with the hose ? car has been idling really rough and throwing the stabilitrac light on, also it rides like it is misfiring, hoping the pcs valve and hose will be my fix.

These do not have a PCV valve. The cracked hose will definitely kick on the Stabilitrak light.

oh ok, i thought i read somewhere that they did have the valve, also i took the intake tube off to clean the throttle body, and the intake hose had dirty brown water in it, what is causing that ?

Moroso makes a filtered catch can that stops all that junk from getting into your intake. I put one on my 09 Suburban. Works great.
It goes in that PCV line.
