    The transducer element in the EGR
    pressure differential sensor likely bad
    or poor connections at the sensor's tubing
    or wiring harness.

    P1506
    Faulty Idle Air Control (IAC) valve
    Idle Air Control (IAC) valve harness is open or shorted
    Idle Air Control (IAC) valve circuit poor electrical connection

    Misfires #5 and #6
    Since you changed the plugs and COPs already,
    this could be electrical harness/connections related.
