I have a ford mondeo 2.5l V6, my engine doesn't idle properly, It cab't find it's idling position. The it's cold and the cold valve is working there is no problem. I have replaced the throttle body cleaned out the air intake and made sure that all the pipes are secure. Now I'm getting a fault code - system is to lean. Can you please advise me

Lean fuel condition could be caused by one of the following below:

1.Vacuum leaks

2.EGR and PCV valve.

3.Low fuel pressure.

4.Dirty fuel injectors.

5.Mass Air Flow Sensor.

6.Oxygen Sensor.

Now I have a fault code P0174 - system is too lean on bank 2, maybe that can narrow down the faults?

Have the compression tested. Check the valve timing to see if the cams are lined up correctly.
