    Default Carbon fouling of only one spark plug

    Hi Pakwheelers,

    I am facing issue of large amount of carbon deposits on one (out of total 4) spark plug. Other spark plugs are in perfect condition. Please suggest what can be the issue ?

    This is only carbon, no oil or anything else.

    scan your car and i guess that cylinder would be misfiring

    Do a compression test,it's possible that cylinder has started burning oil.
