Update on the high idling and rough idling issue with little power:

I did a troubleshooting code using my hand held code reader. I forgot the exact troubleshooting code as I remembered it was located on the coil wire/cable connection between the 3rd and 4th spark plug location. So I removed the valve top cover and saw the coil wire/cable was looose on the 4th spark plug area where the coil pack is located. Reconnected the looose coil pack wire/cable connector. Fired up the engine and back to normal. No shaking vibrations at idling and more power when accelerating. I must have knocked over the coil wire while reassembied the valve cover back on in its place. Issue resolved.
