As a few of you know im having hesitation and stalling issues under load. I just replaced all ignition with cap and rotor, plugs, wires. Im thinking perhaps i could have a weak spark causing these issues, On the distributor cap there is a wire going to a black cylinder mounted just under the window. What is this called? Is there a way to probe it?

FYI spark plugs had white coating but were still good, Dist. cap had green/white corrosion build up on the contacts...not sure what this means.
