all you have to do is disconnect the plug wire to #1 cyl and see if there is spark. 1 and 4 share the same coil. 2 and 3 share the same coil. **i always replace the coil that is not firing and i also install a new ignition module. it always seems that if you dont replace them together it will burn you by doing the same thing a week later.
