98 Lincoln: Are the plugs and wires under the valve covers?

I just got a 98 Navigator. It definatley needs a tune up. During WOT, it will hesitate and start to miss. I will start with the plugs and wires, but...where are they? I found these. Would these be good? Summit 06-0009 - Summit® Ignition Tune-Up Kit Value Packs-Overview – SummitRacing.com

The spark plugs are on top of the engine. Pretty much next to the injectors. Each has its own coil, which is shown in the Summit website. I've never tried their kit so I can't comment on it. Make sure you torque the plugs the proper amount, To tight and they can pull out when the engine heats up. To loose and they loosen and blow out too. If you can't see the coils let us know and we can post a picture.

Take RTG's warning about plug torque seriously. Tightening plugs without a torque wrench on ANY engine these days is just begging for trouble.

I'm a retired ASE Master/L-1 Technician. I still keep current with the latest automotive technology. Visit my blog for cool articles and TSB's: http://www.ricksfreeautorepairadvice.com/
