I don't think the check engine indicators on carbureted cars counted as OBD unless you were extremely generous with your definition of OBD.

The last carbureted cars with sensors and funny actuators on them were proof that the time for fuel injection was upon us.

Honda was one of the last to give up on carburetors, their system was better than the Detroit carbureted systems, but it still blew chunks.


Would a Skoda have a Czech engine light?

Some of the carbureted GM vehicles supported ALDL. Yep, a real-time datastream. The 1986 Camaro Z28 was one of these cars. IIRC it even had a MAP sensor.

1990 Nissan 300zx- codes 32, 33, 34, 51 and 13.

32 and 33 are EGR related
34 is the knock sensor
51 is fuel injectors (turned out to be the harness/connector)
13 is coolant temperature sensor to the ECU

The last two I fixed, 32, 33, and 34 come on and off at random, doesn't really bother me.

The ECU is under the passenger footwell, behind a balsa wood panel under the carpet. Turning a potentiometer on the side of the ECU one direction, then back after a couple seconds makes the CEL blink a series of long-short patterns that gives the code number.

OBD I rules!

I had a 1991 Dodge Stealth twin-turbo that courtesy of being built by Mitsubishi, had an even odder method of CEL diagnosis. There is a factory data port used by the stealership which you can hook an analog multimeter up to two of its pins via alligator clips and the pattern of sweeps of the needle on the meter corresponds with each code.
