Most newer plugs were platinum. So change them every 100K. I'd pull one plug to see how it looks, if yours are original. Changing plugs are cheap insurance of a good running car.

I called my guy (I know it's Sunday but he's a bud) he said that the back plugs are a b--ch and as long as we're not coughing and sputtering he'd just leave it alone. He also said that if someone could tell him how to get at the back without pulling the engine forward. he would appreciate that advice.He said he has never been able to change those back plugs with any easy method.

Have him remove the cross bar between the front struts and on some models you can remove the front dogbone mount and slightly rock the engine forward. Try putting a 2x4 piece of wood between the back of the engine and the firewall to hold the engine forward..

My guy said thanks but as I said he wanted to know an easy way that didn't involve pulling the engine forward. Why do they design cars that require a contortionist or tearing apart just to change plugs. This is not new - I know the designers have a lot of pollution junk to accommodate - guess I just miss the days when you could crawl inside the engine compartment and get at everything.

Well he did as you said, plugs all new with wires too, still it's a pain in the a_s that they design cars so poorly (kids)
