Heres an article that gives Ford Cop checkout, completely useless procedure though unless you have the famous Ford breakout box.
My Mitchell repair stuff has nothing on COP coil specs or testing.
I would suspect since they have no specs its because no one wants to pay me my 99.50 per hour to test a coil X 8.. I know on Lincolns the book says if you have 1 bad one to replace all 8,thats a tuff sale. Heck if a Ford comes in with a miss fire all I need to know is which cylinder, pop the coil out,inspect the boot if its o.k. look at the plug and throw a new coil on it. Such a common problem it doesn't require a lot of testing.
