You can read codes by jumpering two pins on the connector and then read the flashing engine light. This is very early OBD II and late OBD I. I haven't found any one that has the OBD I.5 reader.
The older ones will not show all the codes like the OBD II does. Even some of the codes are not correct.
Terminals "A" and "B" need to be jumpered using a short piece of wire or paper clip.
Pin a is on flat side of connector toward the bottom and B pin is just above it.
Insert jumper, then turn on ignition switch. First code is 12 and will flash three times, then any code will flash three times each.
Could be something like the Crankshaft position sensor, camshaft sensor
I would be more looking in the distributor. Possibly the coil pickup or the ignition module. Look for loose connector.
PM me if you want me to scan page out of my book. We are leaving tomorrow for roadtrip.
