Default Midnight sparking...

Hi guys,

I've had a miss that I narrowed down to old plug wires. I had Taylor 8mm on that are 6 years old and have 30k miles on them. I opened the hood in the dark and saw lots of sparking going on. Swapped some other wires on which took the miss away. Opened the hood again in the dark and saw sparking going on again.

How do I get rid of these?

What brand of new wires did you install?

It's prob the wires. It don't matter if a wire has 10 miles or 30,000 miles if it has been damaged from heat, or just a bad wire to start with.

Okay, so I need some new wires. I really need a good way of routing them! I'd like to have a nice clean look.

Guess I'll do a search on what would be good. Of course if anyone wants to share what they use, I'd be glad to hear. Feel free to post pics too if you have a nice set or have them run nicely.

Just bought some cheapos from Napa... actually not too cheap, $36. But I'll try them for now.

Are you still running center bolt valve covers? I haven't looked at your engine bay since you first put in the zz4. If so I say get some of the looms that will route it right over your valve covers.

I've been thinking of buying a spool of MSD wire and making my own because I'm not too happy with the lengths or routing on any of the wires I've seen so far. If I do that I'll give you a shout and I can make two sets. Of course that's in the pile o' plans right up there with finishing out my shop and the rest of my car projects...

Had Taylors, MSD and went back to original Delcos and routed them as stock. I find myself going back to a lot of original parts on high modded motor!

Good luck

I used NAPA/Belden Super Blue 7 mm ignition wires with the O.E.M. plug holders and wire looms and they work fine.

That's what I bought but they came in 8mm rather than 7. Beldens are good wires and they have a lifetime guarantee. I just did't get to pick the color.

I haven't checked at night for any more sparking. I do believe I need a new cap and rotor however. I think mine is original.

If they're original, they're well outside their maximum service life. Sounds like a Spring tune-up is in order. I'll bet that'll cure your electrical bugaboo problem.

I put AC Delco plug wires on my 89. They were 2-3 inches longer than the Taylor wires I had on there. I wasn't sure where I was going to put all the extra slack at.

But I could hardly get them to click onto the spark plugs. I was only able to get maybe 3 clicked on. The rest I could push as hard as I could, and couldn't get them to click. So, I ripped them out and plan to get something else. I never had any problems clicking on the Taylor wires.

Anyone know if those Belden wires are easy to click onto the spark plugs? And how are the lengths?
