I have this posted at part of another thread but figured it might get more attention as its own thread.

Is there a way to check a COP coil (individual coil) on a Seville, 2000. This is the coil unit that bolts into the valve cover. All four coils are molded into the unit and cannot be removed individualy.

It might be some work, but can you switch it with the one on the other valve head. Also can you post a picture?
