Hi All, 2004 Jaguar Xj8 4.2 runs rough, multiple cylinder misfires, multiple codes but the 1 that sticks out is P1367. Does anyone know where this ignition amplifier is or is it in the ecm? Also if its the ecm are they rebuildable?

 

Electrical Guide Engine Management System: V8 N/A – Part 2 states that IGNITION MODULES AND COILS are combined units (module and coil as one).

All of the coils and plugs were replaced about 2 months ago. Everything was perfect and this occurred all in 1 twenty minute trip. These codes all happened at once p0300(multiple cyl. misfire) p0301( cyl. 1 misfire) p0304( cyl misfire 4) p0306(cyl misfire6) p0307(cyl misfire7) p1313(misfire catalyst damage bank 1) p1314(catalyst damage bank 2) p1316(misfire rate above limit) p0351( ignition coil a primary/secondary circuit) p0354 ( ignition coil d primary/secondary circuit) p0356( ignition coil f primary/secondary circuit) p0357( ignition coil g primary/secondary circuit) and p1367 ignition monitor (bank a) ignition system failure group 1. I thought by other posts that the p1367 ignition monitor (bank A) ignition system failure group 1 was located as separate item or in the ecm as a capacitor. This looks like a trail leading back to a central ignition control for p1367 ignition monitor. I don't have any experience with this problem so any enlightenment is greatly appreciated.

 

Which plugs and coils were fitted?

Pinpoint tests for p1367 here:

I'd worry whether the plugs/coils were the right ones but otherwise check per the above.
