I have a check engine light that comes on after driveing the car for a few minutes. The car seems to run fine all fluids are at normal levels and no other problems are noted when the MIL comes on. The check engine light flashes a code of 55. Resetting the code only clears it for a short while. I cannot find this OBD1 code anywhere. The Overdriive light also flashes when the connector is jumpered. I cannot find any info on this and do not know if it is normal.
All I am asking is what the code means and where to begin troubleshooting.
