Question about 1998 Mercury Mountaineer
My engine light came on and it want go off . My car was put on a machine , the machine showed bank one and two.What does this mean. 1998 mercury mountaineer 6 cylinder 4x4
I recently had the same issue with my 98 mountaineer 6cyl 4x4. mine also showed the same codes for lean banks 1 & 2. That means the engine is getting too much air intake.
After about a month of a constant check engine light, i started to notice a hissing sound that came from underhood, that seemed to get louder every few days.
With a patient ear, i traced it to under the battery tray; which, by the way, looked wet from a leaking battery. Here, in phoenix arizona, batteries take a beating.
Under the battery tray there is an emissions component called the "cannister purge valve a.k.a. vapor manegment valve; attatched to it is the solenoid. there's three vacuum hoses, 2 thick 1 skinny, connected to this whole assembly. the top hose runs from the purge valve to the intake manifold.
Well on the purge valve there was pretty big hole. It was located on the chamber that the top hose connects to. Instead of the intake manifold sucking in a small amount of air from the valve, it was sucking in A LOT of outside air from the newly formed hole.
Just FYI, it took a lot of swear words and some scraped up, slightly bloody knuckles trying to get access to the valve, manuevering and such.

System Too Lean (Bank 2)
What does that mean?
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.
You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
A code P0174 may mean that one or more of the following has happened:
