2001 Windstar Lean Bank 1/2
I have a 2001 Ford Windstar. The check engine light comes on for lean bank 1 and 2 at the same time. (I don't remeber the code numbers off hand but can get them.) Could this be an oxygen sensor problem when both 1st and 2nd bank codes come on at the same time. It runs and idles fine, still gets good fuel mileage. If anyone has any ideas before I start replacing oxygen sensors and looking for a vaccum leaks it would be appreciated.
