My check engine light always comes on after a few minutes of driving. I have an '83 Z28 LG4. I've replaced the O2 and it went away briefly (for about a week) but then started again. Also had the carb completely rebuilt.

I'd like to be able to get the code to determine if the O2 is really the cause, however, Auto Zone and Advance can only check '92 and above. Is there anyway I can get the code?

Thanks!

just ground terminals a and b with like a paper clip or something with the key in the run postion. WARNING do not start the car with them grounded. it will flash a code 12 which is normal for like three times i think then it will so the current codes.

 

Thanks. Also just found this needed information in Chap 6 of the Hayes manual. Complete instructions and codes are listed.

Thanks!
