I have a '95 300D.

I used the LED pushbutton homebrew error code reader and got the following codes. I looked through the cs1000 manual and it isn't really making much sense. Can anyone help me decipher these?

I get these errors:

Port 4: 2 then 8
Port 6: 5
Port 7: 1, which i think is no fault

Any guidance here?

Thank you so very much, I sincerely appreciate your help.
