02 Sport check engine light

[svizzusi]

Okay so my check engine light came on and I am trying to get the car smogged this week sometime because I am selling it. I ran the codes and its PO171 PO174 so the engine is running too lean on banks 1 and 2. I can hear something that sounds like it could possibly be a vacuum leak but I am having trouble locating it... any suggestions?

It's your rubber elbow on the pasanger side by the intake manifold. You can purchase the whols setup or you can just buy the rubber elbow from NAPA.

The Job 2 Sport Tracs have a well known problem with the tube that goes to the Idle Air Control(IAC) valve. It gets a crack in the elbow. But, I don't know if you have a Job 1 or Job 2 Sport Trac. I believe it was in the middle of the year of 2002 that the change happened.
