I've searched this site and Googled with no luck. My 1993 SE is giving me a trouble code of 13, which I'd like to know what might be. The only odd things I've noticed with the car is that when the service engine llight is on, the motor runs slightly rough. When the service engine light is NOT on, the motor runs very smoothly. There's a weird roughness when in reverse.


Anyway, if someone can let me know what code 13 is (and what may be a fix), or point me to a list, it would be appreciated.

Trying going down to Autozone. They will be able to scan your car for free. I had a 1993 Grand AM and I had it scanned when the SES light came on. I cant remember the code, it was a while ago, but, I remember they scanned it for free, gave me the code, and told me what it meant. They may not tell you what the code means anymore, sorry. Good luck.
