    Ok, I had a random misfire to begin with. Decided to re-gap the spark plugs and use Dielectric grease. This didn't fix the misfires it mad them very very bad. Car even acts like its dieing. I don't why this has happened.

    Don't need one. My problem was a broken spark plug.

    The spark plug was loose where the porcelain met the metal. I broke it loose myself. I have no chipped pistons. Only the bad spark plug and poor gaping. All my fault.
