I've got a bit of a whistling problem that's been around for about a month. My CEL came on the other day with a mixture issue (P0174 and P0171). So I'm assuming my issue is a leak somewhere.

I popped the hood today and noticed a huge crack in some hose (no clue what it is). Not sure what it is, and I just need your guys' help to tell me what it is and if I can simply get the part and replace it (I like doing stuff myself).

Could this be the source of my problem? I haven't confirmed that this is where the whistling is coming from as I need to be actually moving the car (just revving doesn't suck in enough air to whistle).
