My 03 S type 3 liter developed a miss and periodic restricted performance notice. When I had the check engine light at checked Auto Zone under "domestic" as in Lincoln it showed code 301 misfire at cylinder #1. Under foreign it showed #1313. When I looked up the Jaguar code for 1313 it said "misfire rate catalyst damage fault bank 1." What doe this indicate? What sort of damage? Thanks, Don R

 

Damage is damage. Fail to fix the cause and you'll need to replace cat as well as the cause.

 

My check engine light came on. and many codes ...300,303,305,1313,1316,0442,352,256,1000.
