- 2000 Ford Explorer Sport
Howdy! I have a 2000 Ford Explorer Sport. Currently, it has a check engine light for P0171 and P0174, stating that it's running lean. I used a smoke tester and found a substantial leak-- one of the hoses is ripped apart. While running, moving the hose causes the idle to fluctuate, and a lot of air is leaking out. The problem is, I can't seem to figure out what this hose is. It sits on the driver side of the throttle body right below the TPS, and runs down into the driver side toward the radiator. I've attached a pic. What is this hose? What does it do? And would this be a significant enough vacuum leak to cause lean codes? Any help is greatly appreciated!
