    I have check engine light on with a "lean code". 4.0 Liter.It seems to run
    fine.Spraying the intake manifold does not produce a change in RPM. Can Gary
    or any other super tech tell me where else I should be looking for this
    issue?
    Thanks

    If you really have a lean code, start with checking fuel pressure.
