Bad engine vibration; bad at idle does calm some as RPM'S increase.
Motor mounts have been replaced prior to coming to us.
Harmonic balancer replaced
Torque converter replaced.
No codes, check engine light is not on.
Engine does run smooth with no misses; just the real bad engine vibration.
Timing is on
We are stumped

Hello,

Those engines have a balance shaft set up in the bottom of the engine in which the bearing can go out. It sounds like there is a problem with it. Unfortunately you will need to pull the pan to check it out.

Please let us know what happens.

Best, Ken
