    The misfires are the effect in this case, not the cause. You have a lean mixture problem based on the short term fuel trim of 25%. The computer is trying to add fuel like crazy to make up for too much air. It can only add 25% and you're already at that.

    That can be caused by a vacuum leak.

    But you also have an intake manifold runner problem too. Find out why you're getting those two codes and look for a vacuum leak.

    Spark plugs would be at the bottom of my list.

    Try new spark plugs, plug wires, and cap and rotor if that even exists on this newer vehicle.

    For sure the plugs and wires. Should be golden than!
