I have a 91 bronco 5.8 FI Auto w/OD 4X4 156,000 miles on it. When I accelerate at about 35 to 45 mph I get a really bad vibration through the whole truck. When I push the OD button to turn it off, the vibration really decreases but not all the way. When I let off the gas and coast like down a grade or just coast it runs smooth until I accelerate again the it starts back again. Any Ideas? Thanks Jeff
