Take it into an auto parts store and ask them to read the code/s for you. Copy down the #'s (P1043 as an example) and post them.
Or you could let us know where you are and maybe a local member with a reader will help out.
Are you sure that it's an LB7? They also made LLY's that year. (Just making sure)
