2001 XJR 100k: P0300 P1316 P1111
Started car up and suddenly it's miss-firing ... After .5 mile restricted performance came on, used my scanner and it returned ... P0300 P1316 P1111. Anyone have a similar tale ... I'm hoping it's just a coil or a spark plug. :/ Any help/suggestions greatly appreciated, thanks.

My xjr was also miss-firing at one point and also got the restricted perf, and shortly after my fuel pumps went out. i dont remember the error code tho srry..hopefully it is a minor issue with yours. My tale turned into a horror story. I changed the fuel pumps and found out i most likely have a blown head gasket..good luck, lmk if you find out what the problem is.

All the codes are pointing to the left bank, all cylinders. Neither individual coils or a blown head gasket should invoke all cylinders. Fuel is a common link, contaminated, pressure or blocked injectors. A fuel pressure test is a cheap place to start.
There is a OBDII code list in the FAQ sticky at the top of the XK8/R forum. I would suggest resetting all codes and see what comes back up.
