>> only when there is no pressure on the  accellerator.
>>
>> It doesn't happen when the cruise control is on,  presumably because it
>> always keeps some positive pressure on the drive  system. It doesn't
>> shake the car or affect its handling or power. The  lightest feather
>> touch on the accelerator stops it, but it starts  again 1 to three
>> seconds after I let off the gas  completely.
>>
>> I would think if it were a blocked catalytic  converter, it would be
>> worse when accelerating, and the same if it  were the fuel pump. It
>> doesn't seem to fit a wheel bearing or a brake  problem either. I
>> worried about a U-joint on the driveshaft, but I  found very little play
>> in the system when I shifted from reverse to  drive and back (while
>> holding the brake with the truck motionless),  and no noticeable 'clunk'
>> sound.
>>
>> Any ideas? Keigan is  driving the vehicle, so if it IS a U-joint going
>> out, I want to know  that and get it fixed.
