engine running lean in bank 2 on 4 cylinders

It is running lean.. Which means it is not getting enough fuel.. Clogged fuel injectors? Could be a couple other things too.. May want to take it to have it diagnosed..

i put it on diagnostics last weak at the ford dealer and all it told me was the engine was running lean in bank 2 with cylinders 2,4.5 and 6 misfiring

Pour in a whole can of Seafoam fuel conditioner with a full tank of gas. If that doesn't work then check the fuel pressure. If you're handy and have time, swap the injectors from 2 to 1, 4 to 3 and see if the problem follows to those cyliders. If so, injectors are bad. Best at this point to replace them all. Good luck!
