[T3] gas mileage, voltage, etc.

I can check while driving later today. I didn't have the time to hook
everything up before leaving today.

I didn't check the resistance of each wire. Rather, I checked that
each wire was firing last time I had the timing light hooked up.
Wouldn't an intermittent miss also show up under load and not only
periodically at idle? General driving is fine and responsive as always
though I should maybe add this one irregularity: three times last
week, I experienced a slight bit of hesitation or a miss when trying
to accelerate hard up the steep portion of a bridge in 2nd. It wasn't
quite as jarring as a full miss but felt like slightly more than
hesitation. But I drive that bridge sometimes twice a day and it
didn't occur regularly and hasn't shown up since last week.

> Any sign of clicking relays when the engine speed inexplicably drops?

No clicking relays. I just hear the idle speed drop and as it gets
rough, I feel it in the seat back and through the body of the car in
general.
