Ahh.... Somehow it sounds like you might be heading into the darkness if you
do purchase the car.
I checked with my son, who had an '89 Accord. His ECU got wet in a flood and
was damaged - replaced with one from a wrecking yard. He said he didn't
think it produced any codes when it was working normally.
