Welcome to AF,

What was the code number.

I would look for a vacuum leak, spray carb cleaner on the vauum lines and intake, if idle increases you have found your leak.

lean code means there is unmetered air entering the system after the Mass AIr Flow sensor before the throttle body.

Bank 2 on a Ford is the clyinders cloest to the radiator or driver side of engine.

The leak would not necessarily need to be before the throttle body, it could also be an intake manifold, manifold vacuum port, PCV system, etc.

I stated that wrongly shorod, I was trying to say that the MAF sensor was just before the throttle body and need to look at vacuum lines and intake gaskets like you say.

thanks for clarifying that.

The rubber tube going from the PCV to the intake manifold FORD 2F1Z6C324A PCV VALVE AND VENT HOSE. About $25 at Ford no tools required to replace it . Thanks on all
