I had my service engine soon codes read today.
I got P0171, P0174, and P0300.
In english that is lean bank 1, lean bank 2, and Multiple cylider misfire.
A tune up and new O2 sensors was recommended.
Does this sound reasonable?
What would cause a multiple cylinder misfire? The engine sounds and feels smooth.
Also, when you get a lean reading, does that mean the O2 sensors are bad, or does that mean they read a lean condition and are working fine?
I think this thing has 4 O2 sensors, so I really dont want to replace them unless I have to.
I have a 2000 Explorer Sport with the 4.0 SOHC.
Thanks
