Dang, i'm sorry to hear that. New o2 sensor helped a little, but the vibration is so bad that it doesn't smooth out until about 2000 rpm. From there up, she smooths out enough that a passenger might not notice. Wiped out the inside of the distributor too, to no avail. Not like a miss, all cylinders feel like they are firing. Will hang in there. Thanks again Steve.
