As Doc pointed out there are no retained codes in memory on early federal cars. They do have real time fault codes as expressed in On -Off ratio testing. It can be read off pin #3 in the diagnostic connector on the left fender. There is a special tool but it can be read with a scope using the technique explained in the DIY article "evaluating engine controls".
