Corroded coil post
Hi -
Replaced plug wires on the Bonne yesterday. #2 coil post was all corroded up. I cleaned it up before putting the new wire on. Bonne seems to be running fine. Is this an indication that the coil is going bad and should be replaced??
Also, do I need to put the metal plug sleeves on my new wires???
Thanks in advance for your help.
Happy New Year to all!!

it means you need to put goo on there to prevent corrosion. You can check the coil packs cold and warm with a digital multimeter.....
Yes you want the 3 metal heat shields.

Please clean that corroded post and then use dielectric grease (lightly) to coat it and the ends of the plugs. This will keep the wires from sticking to the plugs and ensure a good long term contact.
If the car is running well, I personally wouldn't bother with testing the coil packs.
On the metal sleeves, you should have moved them over to the new wires.

Thanks for the replies. I went and got some dielectric grease today. Plan on working on her tomorrow morning. I kept the metal sleeves. The boots should come off alot easier this time.

If so, change them.

Didn't look for the factory numbers on the wires. Sleeves just slipped over the boots. My SSE has about 140K miles... Lost some mileage with the infamous instrument cluster electrical problem. I was fortunate enough to get an ebay replacement that has worked great, but added 23K miles to the odometer.
She was just starting to have a misfire problem first thing in the AM and under load. Replaced the wires and found the corroded coil post. Had a rough time getting the 3 plugs on the firewall side with the metal sleeves off the spark plugs.
I'll grease up the coil ends and plugs, and put the metal sleeves on tomorrow. Thanks

Ya - twist, pull, tug!!! I sure was glad I had new wires in the garage with me!!! I'm hoping that the dielectric grease will make them easier to get off next time!!

Nope. The hard sticking part is the rubber boot around the shaft of the spark plug. I routinely turn them about 270* to get the rubber to *pop* loose before they'll pull off easily.
