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
