Question about P1320 warning light code:

My warning light is on and I took my car to Auto Zone. They hooked up their dianostice computer and it said P1320, Manufacturer Control Initition Sysem or Misfire.

Anyone have any idea what this means? I appreciate any responses. Also anyone know where I can get a service manual on my car for a cheap price?

sincerely,

Steve

I posted the above in the wrong room. My car is a 2000 I30 not J30.

thanks
