Yes, the light is steady on all six.
To replace the wires I will need to learn how to make my own. These wires were made by Bill (although I swapped a cracked boot on one of them) because they have to have AMC/Jeep boots on one end and Dodge/Eagle boots on the other. Making plug wires is probably a skill I will need in the future, so I am happy to learn now to do it.
Last time I checked the cap and rotor were fine. But the plugs were black. I didn't think a dirty plug could cause a misfire (only oil-fouled plugs), but I just looked it up online and apparently it can, because the carbon buildup will create a path to ground that sidesteps the air gap on the plug.
