212k miles... if the O2 sensor is the original, this is a
good investment.

IIRC from some discussion here recently about this
(reinforced by some comments in the manual), for my fuel
injected 91 Civic, the computer does this to assist the
alternator, now under higher load from the electrical
accessories. When I turn on the headlights or defroster,
say, I see increases of only around 250 rpm, though. So on
my 91 Civic, it's quite noticeable, but not as stunning as
the revving you're seeing.

Hopefully that will draw other comments. The net has sites
that talk about how to maintain a car after it's been
sitting that long. Might want to google.

I hope you noticed the manual is /free/ online. :-)
