sitting in traffic from the auto fair and finally got out, then started down 485 and the check engine light came on. pulled over and pulled the codes:
Code 12
code 51
code 37
code 55

started the rc back up and the light has been off since then. it seemed to run fine during this.
thanks for any help.

12 means battery has been disconnected in the last 50 key on-off cycles. 51 means lean fuel/air ratio. 37 may be normal. Its a code for the lock up converter. But if you dont' have a lock up converter then the code would always be there. 55 means end of codes.
