I had this going on and replaced my valvetronic motor about a month ago. The tools to do it are more than the eletric motor with the built in positioning sensor, smh. replacing the eccentric shaft while in there is optional, replacing the eccentric shaft roller bearings is probably adequate.

Also clean walnut blasted intake valves helps a nice smooth idle.
