don't need obd tester for obd0 - the ecu flashes code readings direct.
reset the computer by pulling the hazard fuse for 20 seconds.

look under the carpet on the passenger side to see the ecu. turn the
ignition on, [but do not run engine] and count the number of flashes of
the red led visible through the central window of the ecu. then go to
tegger's faq's to translate the code. code allows remedy!

Theo,
I suggest that when you visit Auto Zone or some other auto store that does
free tests and ask them to determine the code that is displayed. If no
codes are displayed--you may have to wait for the light to come on before
you have it tested. The code should tell you the problem. In most cases,
the light remains on until it is reset. I have my own OBD tester that I
purchased for only $69.00. You might consider buying one. Make sure that
it has a reset button on it.

The check engine light comes on occasionally in my stock 1990 honda
civic wagon 2WD 5-spd. This happens about once or twice a month when I
am driving on the highway. Usually it only happens when I am in a hurry
and the car has not been driven in a while (ie overnight). I usually
get to the highway in about 1-2 minutes after starting the car, and
then it's a sprint downtown at 130km/h @ ~3500rpm. Sometimes when I do
this the check engine light comes on after about 1 minute on the
highway. The light then stays on for the rest of the time the engine is
on, but if I turn the engine off and immediately on again, the light is
not on anymore.

Any ideas what might be causing this and if I should be concerned about
this?

Thanks!
Theo
