2000 ranger 4.0L OHV EFI
I passed by the dealer he checked and no egr system on my truck.With my vin #
and 8th digit X he confirmed my truck was built before july 2000 and no egr system.Told me lean code was a vacuum problem. After reading all the help on this site i found and repaired the problem. I changed the 3 rubber gaskets on the upper intake manifold. Truck runs great and no more check engine.
Thanks and hope this helps others. http://www.explorerforum.com/forums/...d.php?t=171819
