Cadillac Repair: Check Engine Light..., cadillac fleetwood brougham, cadillac fleetwood

Question
I wrote in about a week ago about my check soon engine light coming on....Anyway, I finally got around to doing it, nd the last person I talked to I think was Bill, and he told me how to do the "test" to see which code(s) came up, and I have them....the codes that came up were as follows: 16, 26, 30, 52, and 67.  The car is an '84 Cadillac Fleetwood Brougham with a 4.1 Liter Engine...Those are the codes that came up, and I'm supposed to let you know what they were so you could let me know what each one is and /or what's wrong and needs to be fixed or taken a look at.  Thank you for you time!

Answer
The first thing you need to do is CLEAR (erase these codes and re-enter into the diagnostic procedure and after the codes appear Push and hold the OFF and HI buttons until you see .0.0 displayed and release the buttons.

Drive the car and then recheck to see if any of the codes reappear and how many times the same code appears.
