Followed the thread so far - enjoying the progress. (And the mysteriously "healing" missfire.)
Looks like a fun little car. I had a plain jane Civic 1.5 of that vintage for a short while and it was the first car I ever owned that surprised me with its mileage: 53 mpg (US) / 4.4 L/100 km just by taking it easy (90 km/h / 55 mph cruising) on a back roads trip.
There was an old lady in town who had a ridiculously low-miles 5-speed exactly like mine that I had my eye on (the car, the car!). Unfortunately, a tree fell on it in a storm, and my dream was squashed along with the car.
I'm a bit envious!
