If you mean pull the plug to see if its firing, no. I intend to do that tomorrow night when I get home. I did pull the plug wires one at a time, didn't seem to make much difference. While i'm pulling the plugs, I might as well check compression.

I meant for a possible indication of a specific cylinder miss, as well as an overall indication of mixture.
We know they fire, or at least most of them some of the time.
I was hoping it would help give an indication of going way lean or something like that mostly.
