Hadn't had the Cobra out for a cruise in about 10 days, so last night the wife and I go out for ice cream. Much to my dismay, we notice an intermittent vibration at speeds above 60mph. Vibration lasts for a second, then stops. Then starts, then stops. Then starts, then stops. You get the picture. Can feel it the strongest under my seat, but the steering wheel vibrates a little, too.

Happens in 4th and 5th gear at highway speeds. No vibration below 60mph. Very weird for something like this to develop as the car was just fine when I drove it 10 days ago. Can you guys give me some quick tips on the things I should check which could be causing this??


Thanks,

Russ
