1997 Mercury Mountaineer AWD
1997 Mercury Mountaineer AWD born on 7/24/97 first year they were made.
Manufacture date 7/97
Included an extra segment on why the Differential Pressure Feedback EGR
(Exhaust Gas Recirculator) Sensor
goes bad. I tried to show the white residue inside the vacuum lines which
is corrosion caused by moisture. There is a TSB (Technical Service
Bulletin) for Ford, Mercury and Lincoln SUVs for that sensor because it
was originally manufactured with aluminum which corrodes in the presence of
moisture and is a common cause for the check engine light of said vehicles
to illuminate. The new sensors are now plastic and have the vacuum lines
much further apart. On the 5.0 Liter engines, you will find this sensor
next to the intake manifold and the transmission dipstick between the
engine and firewall. Takes 5 minutes to change with right tools. The screw
next to the transmission dipstick is the hardest to get to and will require
an extension. I replaced the EGR(DPFE) sensor, that is why I am showing the
old one in my video.
Transmission Problems (Mountaineer/Explorer)
I own a 2002 Mercury Mountaineer and I have been experiencing some tranny
problems with it. My transmission refuses to shift past 45 mph causing a
lot of problems for me. According to many auto review websites this car and
the Ford Explorer counterpart are not strangers to this sort of problem.
