Ignition wires, again
 
Yesterday when I was pulling my SL1 into the yard to change the oil, my day was brightened once again with the glow of my SES light. From the way it tripped on and the increased noise in the AM radio I guessed that I had yet another camshaft position sensor problem.

And once again an ignition wire had a bad connection. This time it was the #4 wire at the coil end; it was all powdered over. I cleaned it, the car immediately ran smoother, and the light went out on its own today.

The question is, has anyone found something that keeps this from happening? The last time (#3 wire this last spring) I tried using KOPR-SHEILD, a connection goo that looks like copper antiseize and is every bit as messy. It's didn't help. It wasn't meant for automotive use and the temp rating was low, I didn't have high hopes for it.

Has anyone come up with something that really works? I've never had a vehicle that ate ignition wires and connections like this before.

What you have to find is a set of wires that have the high quality stainless steel connectors. Then you have to just put them on and try real hard to not be connecting and disconnecting them. Clean the coil tower aluminum connector and wipe the barest amount of silicone insulating grease on them. Install new wires. This is as good as it gets.

I have had good luck with Magnecor 7mm wires. You really do not need the high $$ big fat ones.

You can buy them direct or scout the internet with Google for a discount.

Somebody that works on Saturns a lot told me that 7mm wires are the hot ticket for Saturns.. not sure if that is true and why but next set I buy is going to be 7mm especially since oldnuc reccomends them, maybe he will explain why 7mm work better for saturns???? hint hint

All of the actual wire core is usually the same size in all the different sizes. All you are buying is thicker insulation and usually a pretty color. The DIS system does not generate voltages high enough to warrant a thicker insulation. The reason for staying with 7mm is all you get with the larger diameter is a thinner wallet. You can use 8mm and it still fits in the stock clips but its a bit pinched which is not good either.

You will find some that have a larger diameter wire core and this will function better with the high voltage systems. You will know if you need it though. You don't with a stock Saturn ignition.

Thanks OldNuc, looks like I'll have to do some shopping. Hopefully I'll have one less problem when the snow is up to my waist.
