Expedition code 0171
Has anyone had any experience with the check engine light coming on with code 0171?
Other that the light coming on I have not noticed anything else.

Thanks!

How old and mileage?

Suspect bad plastic, rubber, or seals on your PCV or EGR system.

Have a smoke test done to help pinpoint unmetered vacuum leaks.
