Hi Knight,, nice to meet you .. Seems like a drastic problem for your 96..Jim Blakes on a good path,, I dont know what he does for a living but he knows his Hondas,, its true a bad crank pulley will cause a vibration,, the problem stems from the rubber silencer that your crank pulley has built in that seperates the crank connection to the pulley section,, This can seperate causeing the crank pulley to wobble from side to side while running,, thus a vibration.. But it usually isnt that bad to vibrate the dash or ft Bumper,, Notice I said usually?? Another thing I look for is a bottomed out motor mount, transferring all engine vibration directly to the frame, another is a miss timed balancer belt,another is excessive High pressure side of your AC system..Knight,, the list is endless,,
