I bought earlier a 1998 XJR only for parts donor to my front damaged 2000 XJR, but now as the newer car's repairing has ended - and I slowly forgot the lot of work with it -, I got the thought, I "have to" rebuild the donor too. But firstly I wanna check that the engine and the transmission is good. Every other used parts is not too expensive, so these two can forcing me to rebuild or not.
Firstly I solved the gear box problem (fixed 4th), that was caused by low oil level, and the gear lever arm's 2-3-4th selector needle jumped out from the switch in control system.
The next problem is the 'restricted performance', and the code is P1367. I checked the coils (all is OK), but as this fault code means there aren't sparks at the 1A,2B,3B,4A cylinders. I checked it by my eyes, there are not sparks. All of the two ignition coil module gets 5V, and the wiring is not opened between the coils and the modules. Actually I did not checked the wires between the ignition control module, and the pcm (ecm), but how common is this problem? May I buy a new or used ignition control module, or is there a chance for something other that causes this problem?
Your question seems to be "how common is this fault code?" I would guess that its pretty rare. Do you really mean, "How do I diagnose the problem?"- You might try swapping the ignition amp modules, reset the codes, and see if the code for the other cylinders comes up.

Looks like there are a number of used ignition control modules on the various Ebay websites for prices in Europe at the 30 pounds or so range (with shipping) - in the $40 range in USA.
You know the part number, but for other forum members may not know it, the part# is LJA1450AF.
A new one from Jaguar would be in the $400 price range.
Here is a photo of the 2 ignition control modules from Ebay listing showing their location on what looks like a molded piece near the brake fluid reservior. They are not at that location in our 2001 XJ8 and I could not find them.
