A lean fuel condition can be caused by:

* Low fuel pressure due to a weak pump or leaky fuel pressure regulator. (Use a fuel pressure gauge to check fuel pressure at idle)

* Dirty fuel injectors. (Try cleaning the injectors)

* Vacuum leaks at the intake manifold, vacuum hose connections or throttle body. (Use a vacuum gauge to check for low intake vacuum)

* Leaky EGR valve. (Check operation of EGR valve)

* Leaky PCV Valve or hose. (Check valve and hose connections)

Thanks for the response. I know for SURE it isn't the EGR valve and we checked everything for leaks - we can't see any external leaks. But I really appreciate such a speedy response and we'll go through what you gave - I have a specific code that starts 14 but. I don't have all of it with me right now.
