About 20 years ago I went into my friendly local "Foreign Car 
Specialists" with a capacitance meter and measured every cap in their 
inventory. I wanted to see whether the different caps were different 
in capacitance or in mounting, or both. I was astonished to find that 
ALL the Bosch caps were the same capacitance regardless of whether 
they were for a car with a standard Kettering, CDI, or transistorized 
ignition. IIRC, that number was 1.5uF, but that was a long time ago. 
I should measure some again.

This is really the only way to check a coil, but in this case it's 
important to keep in mind that (I hope I'm thinking of the right car) 
he's having trouble with #3 cylinder. That could only be caused by 
something specific to #3, not by something shared by all 4 cylinders.

The one exception I would be willing to make to this would be the 
dwell since marginal dwell might just be a little more marginal on 
one cylinder due to wear differences in the points cam lobes.
