1999 Chevrolet Silverado 1500 4.3L Engine/Exhaust
Engine vibration is very noticeable at 1000 to 1100 rpm under load. Appears worse when cold. Have checked mounts, changed exhaust as noted. Has anyone seen this before? On this vehicle one side of the exhaust has a donut and the other has a flat bolt up flange...
