Bogus OBD1 codes

I've been having a sort of random issue lately. I've been running KOER tests and it's showing me many fake codes. I get codes that aren't even listed in the book at times, like code "9". It's different each test. I ended up buying a new code reader to see if there was a difference and it's the same scenario. I also tested another ECM for another purpose and the same thing... Grounds are good. The next thing I might check is corrosion at the test terminal. Anyone run into this problem before? I suppose it isn't "hurting anything", but still trying to figure it out.

1) Why are you running KOER tests? If there is something wrong you do the KOEO self test and repair anything there first.

2) What fake codes are you getting?
