BTW, same thing (first time maintenance at 170k miles, with no problems before or after) on spark plugs (yes, original at 170k with no problems!) and upstream O2 sensors.

First time change on AT fluid (twice) and front diff oil, with noticeable improvement.

The car really seems perfect now and I've run out of things to do on it.
