I just did the KOEO test on my '94. From what I've read in a couple places, only 3 digit codes should be generated by the computers for this model year. Mine just gave me "33". I did it twice (two tests, each time 3 flashes - pause - 3 flashes, long pause and flash and long pause, then again 3 flashes - pause - 3 flashes). It was pretty clear. If this were an earlier year ('89-'91), this would mean "EGR opening not detected". Should I just assume this is the case? Is something wrong with the computer?
