Right kick panel. Yes it stores codes but in all the -years- I've worked on those cars, I've never seen one store any useful information. The code set is -never- what's wrong with the car. It will set a code for the ignition when the MAS is bad. When the ignition is the problem it will set a code for the fuel temp sensor etc etc. SOmetimes it will have a half dozen codes set and none of them are what's wrong! It's a waste of time bothering with reading them on that model car.

I disagree. At least on my 1988, it was a godsend. It correctly reported that the MAFM was faulty; when I replaced it, the check engine (yellow) light went out. (The 1987-89s have a check engine light, and I'm not sure the 1984-86s do.)
