'87 Honda Accord LXI Sedan (Automatic) with 200,000 miles. Still in great
shape and runs well.

More of a curiosity item than anything else - when the engine is running and
the heater is blowing, the heater blows very strongly when accelerating the
engine, but drops down when idling. I haven't checked thoroughly to see if
other accessories are affected (interior or exterior lighting).

Any ideas?
