    how many miles do you have? Hows your air clear? Did you change your spark plugs at 30,000?

    They say change them at 30k but they use a copper plug, when I change mine it's getting platinums so I dont have to do it again

    If you have to pull them to re-gap them at 30,000mi, might as well just replace them.

    Expensive multi-tip platinum wonders are a bit of a waste on these engines.

    Change your plugs John. Make sure the new ones are gapped at .040-.043,and go with the stock plugs.platinum won't do anything for these motors....and unless you are sc'd.....the iridiums won't either.
