not sure if it's the same exact problem, but another thing to check. I also have new plugs and wires and it still does it.
Pull off the MAS and see how it looks. I would start there. You can unplug the MAS and see if that makes a difference in how it runs. If there is no change then you could be looking at needing to get a new one.
