While driving my truck, I can hear and feel a vibration that seems to flare up and then it slowly clams down. All gauges look good. Engine seems to be running well. I start to hear the vibration and then get off the gas and it stops. If I get back on the gas it returns. This seems to go on for a 20-30 min. period. Then it seems to go away. No noise or vibration. It is very strange....
