Ok I just ordered this
Ford 10 Ignition Coil DG508 10 Motorcraft Spark Plug SP479 B267 10 IC170 New | eBay http://www.ebay.com/itm/350779798877
I am going to change the coils. This thread, and another I started on another forum have suggested multiple times that the COPs might be bad. Figured, might as well change the plugs while I am at it. I have no idea when/if they have been changed since stock. The coach now has 91000 miles on its odometer, so might as well change them, judging by the terrible maintenance on this unit from its previous owner, these more than likely have not been changed.
