Keep us posted about the sluggishness it could just be that the trans needs to adapt to the change.

did you get the whole under dash removed or did you try the diy with it just pulled down?
If off then someday if your evap sensor goes it will be old stuff for you to r/r it.
And after crawling under the dash,plugs and oil changes will be a walk in the park.

who knows anymore what the dealer would charge when one of our members got quoted a GRAND for plugs on a E320 !!!!!!!!!!!!
