    Could these codes indicate the ignition coils and spark plugs need to be changed or is there additional repairs needed.

    Those are historical codes. They are not current or active codes. There is nothing to worry about unless they are current codes.

    How many miles on the car?

    Yep; It could've happen with a loose gas cap on the emission control code.

    The cylinder #2 misfire may indicate something - check your engine coolant level (passenger side reservoir).

    I cleared the codes the 1st time and the 2nd time I scanned it, they reappeared.

    When the engine starts it begins to rough idle until you turn it off.

    The gas cap is tightened.

    It has 245k miles.

    Please provide a little history about the car. Has the head gasket or engine been replaced?
