check engine light came on. 44,000 miles, 6 cylinder
mechanic read the diagnostic code which said
cylinder 5 misfire, he said i needed new plugs.

had a mechanic change them.

check light came on again later.
i looked at the new plug ,it was a one electrode platinum.
right on the hood of the car there is a sticker there
that says dont use one electrode, use two electrode plugs.

could this make a difference ?
do you really need a dual electrode plug
in this car

thanks
