1995 Concorde warm up difficulty

    My 1995 3.3L Concorde starts fine and runs perfectly when warm, but for
    several minutes during the warm up it has a power problem.
    This occurs a few minutes after starting, from a cold overnight start or
    from a few hour stop. After several more minutes it will be OK.

    It starts running rough, missing slightly, doesn't respond to the
    accelerator and has backfired when I push the accelerator hard on a hill.

    BTW I replaced the EGR hoses and valve about 6 months ago. The hoses had
    disintegrated, but the valve was still in reasonable shape. The spark
    plugs were replaced at 60K miles.
    This engine is in very good condition, only about 85K miles with oil
    consumption and fuel mileage as when new.

    Hopefully one of the experts here can put me onto the solution.
