My 2002 3.2L XJ8 was running perfectly yesterday but as I was parking the yellow MIL light came on together with 'Restricted Performance' and rough idling. I scanned it and these are the following DTC codes;
P0303 - Cylinder 3 Misfire
P1316 - Misfire
P0341 - Camshaft Position Sensor Circuit Range/Performance (Bank 1)
P0353 - Ignition Coil 'C' Primary/Secondary Circuit Malfunction
P1000 & P1111 - Which I believe are just test status codes
Does the rough idling throw out the camshaft sensor?
Then I got two further warning messages ASC and TRAC Unavailable. My day was quickly getting ruined.
I left the car a couple of hours and went out to move it to somewhere I could work on it and the MIL light and all messages had vanished and the car was running perfectly again.
Has anyone experienced anything similar and what was any solution please? Any info would be appreciated.
Thanking you in advance
I would suspect a faulty coil pack on cylinder 3 which is causing the misfire.
Once changed you'll probably find the other codes will disappear.
After clearing the codes you should have the P1000 which changes to P1111 after the drive cycle is completed .
Let us know how you get on.

Thank you for your reply.
At present she is still behaving. I was surprised it resolved itself. I'll take her out for a run and see what happens.
If it does reappear I may swap coil packs to see if the fault is transferred.
I will post and let you know what happens.
