My check engine light came on tonight. Since it is Christmas Eve it was almost impossible to find someplace to run a scan on it. I did manage to get someone to scan it and it comes up with these codes:
P0300 Random/Multiple Cylinder Misfire Deteted
P0301-P0307 Cylinder # Misfire Detected
P1316 Manufacturer Control Ignition System or Misfire
(DTC Pending) P1111 Manufacturer Control Fuel Air Metering

The car seems to be running smoothly so I plan on continuing to drive it until I can take it to a dealership (probably Saturday). If that is not a good idea then let me know.

I have an 03 STR. Has anyone else had these codes before? I saw a TSB(S303-19) that has these same codes. Does anyone know if TSBs are fixed for free or would it be covered with the Jag extended warranty?
