Sometimes cars don't like the platinum plugs. How old is the car and what model? If it has a larger engine say like in a Jeep 6 or 8 cylinder then use the platinum. Smaller older cars do better with copper plugs. Have owned both so I just go with the engine size and the age. Just my 2 cents.

Double platinum plugs can last a 100k miles but not the single platinum plugs.
