Cracked for sure, the plastic was not even aligned. Pretty sure its been that way since I got the car years ago.

Plugs will be next. By the way, I do feel a shock if I touch any wire. I think I will change plugs soon. I read a bad plug may cause this issue. I will also clean all the contacts and mounting surfaces for the coil.

If you are getting a shock, the wires are leaking. Change the plugs now as you will damage the wires if the plug gaps are very large.

agree with the above post. worst case scenario is the ezl unit also.

check the coil where it mounts to the body. any "white" you see on the coil body where there transformer core meets the bracket, that's leaking voltage, also. very common. any extra gap the spark has to jump means more amps from the coil. more amps means a tired coil and the shortest path to ground. that's why the white on the coil and the corona you see around the wires. good luck, chuck.
