 Coil-to-distributor wire sparking

I have just noticed that I can see some sparking from the coil-to-distributor wire. It was actually arcing to the air intake if you can believe that. It would also arc to the cruise control throttle wire if it was close enough. I'm sure the wire must be bad (its original) but I wondered if there's anything else I should check when replacing it. The plug wires are only a couple years old. Have to wait a couple days before the wire is in anyway. Any input is much appreciated.

look for a carbon arc line.
scrub it off with one of those green scrub pads.

You either have a bad coil or a bad coil wire.

Thanks guys. I checked the wire for any marks or cuts etc but found nothing. I will put the new wire in when I get it and see if that fixes it. Otherwise I guess it might be the coil. Is there a way to test the coil?

There is a sticky in this section for FSM's. The one for the '93 will work for ya; just make sure you're looking at the right stuff, as both 22RE and 3.0 info are in it.

Thanks, found the specs. Will test it out tomorrow and see how it works out.

OK, I put in the new wire from the coil to the distributor. I measured the resistance on the coil and got these readings:
Primary coil - .8 (200ohm scale)
Secondary coil - 12.8 (20K ohm scale)
These readings were taken after my 1/2 hour drive home so from what I can get from the FSM they seem to be in spec. (I think).
The wire still seems to spark a bit if too close to something else such as the wire from the cruise control. I can see little sparks going from one to the other. Is this normal?

You're getting a spark jumping out of the coil wire because that's the path of least resistance for the spark. You've got high resistance somewhere downstream from there. Check to be sure you've still got a carbon button left in the center of the distributor cap. Also, using an ohmmeter, check that there's continuity in each of the plug wires.

Thanks for the reply. I put in a brand new wire from the coil, and its still doing it quite a bit. I will check the distributor and test the continuity in the plug wires too and see what's up. Is it still possible its the coil or would it have to be something downstream from that since spark is being generated?
