I've changed the plug out as well as swapping coils which lead to no change. If the misfire occurs during higher speeds, it could be a problem with the operation of the overdrive gear or a chattering clutch in the Lockup Torque Converter. A Compression Test and an engine idle Manifold Vacuum Test are two very important methods of determining the mechanical condition of the engine.
