850 idles rough almost a shake... also at start up, after getting warm seems to subside in Park or Neutral...still shakes in drive or rev. Has a P0410 code

 

Probably a vacuum leak somewhere. These cars are known for that.

 

I was unable to find the definition for P0410 in my manual.

Retiring engine mounts?

See attached FYR.

As above, check the motor mounts and for a vacuum leak. It should idle smoothly. WHen was the last full tune up done?

 

same problem i was maybe thinking tranny
put allnew plug wirescap and rotor did nothing
replaced upper motor mount also so open to ideas

 

Do you hear a misfire from the muffler? Try some injector cleaner and also clean/check MAF sensor.
