My thought, too, Jorge. I replaced most of the ignition coils on my Lincoln over a 6-8 month period. It seems logical to me to think that sometimes replacing one unit of several in a system might put additional stress on the remaining parts, thus causing them to fail, too.

Seems logical, but then I'm not a mechanic.

No. The coils have nothing in common with each other ( aside from the age factor ).
I believe Ford and some others have had quite a few problems with coils.
For the price of them, replace one-at-a time.

Like we say down South. "If it ain't broke, don't fix it."

Sometimes I see just one coil go bad, and maybe another a couple years later, and there are other times when you see two coils go bad in succession of a couple weeks apart.

You never know when one is going to fail, so you are smart to carry one for emergency purposes, but you may want to get the supressor end along with the coil.

I already replaced wires & supressors. They are brand new.
Thanks, Jorge
