My 98 Grand Marquis is surging at highway speeds. Seems as though this is a common problem with this car. My brpother has 99 CV and he had to replace spark plug coils. Could there be anything else causing this? By the way, my brother's 99 CV needs a new ignition switch because his shorted out. I'm wondering if mine will do the same? Seems like thesed are all common problems.
