2001 5.4 engine is firing on all cylinders and is getting good mileage on a test done last week. There is a vibration in the engine as though I have solid engine mounts?? I know it's the engine because the flex plate, torque converter, on back to the diff have been rebuilt.
I have removed the belt and ran it sitting still. Still had the vibration. I replaced the harmonic balancer, same. I replaced the L and R engine mounts and the trans mount. I visibly checked all over for visible vacuum leaks or anything binding to the frame or body. ?
