I have recently purchased a 94 Olds Delta 88 Royale. It has the 3.8 v6 and has 82400 miles. How do I use a diagnostic code key to figure out the error code. A guy at Auto Zone gave it to me to help me with my problem. I have found the plug under the dash but am not sure how to use the key. Can you help?
