Can a bad PCV valve cause a P0174 code?
Ford Expedition lean codes could caused by a leaky PCV hose. If a car has a check engine light on and has P0171 and P0174 codes stored, the most likely cause is a vacuum leak. These codes are set by the car’s computer when it sees too much oxygen in the exhaust. This does not mean that the oxygen sensors are defective.

Can bad spark plugs cause a lean code?
A P0171 ( too lean, Bank 1 ) code is most often caused by a vacuum leak downstream from the MAF sensor or a malfunctioning MAF sensor. Bad spark plugs could actually cause the opposite code ( too rich, bank 1).
How do I fix system Too Lean Bank 2?
Will a clogged air filter cause a lean code?
If the filter is clogged or excessively dirty, this is enough to impede or restrict the air flow, hence resulting in a lean running condition.
