Welcome...You need to read your fault codes, otherwise you are just making guesses. Best to buy an inexpensive OBDII code reader and post your codes here and folks will help you.
Check your convertible top pump fluid. If it is yellow, replace it with Pentosin CHF-11S which is green in color. The old yellow fluid had a jelling problem.

It's impossible to maintain the V8 on these vehicles without access to a code reader. Even a basic one that just reads generic codes will pay for itself in troubleshooting your current engine problem.
You also need to refer to the specific DTC list for your model year. Codes are accurate - descriptions from any other source than the Jaguar DTC list can often be wide of the mark and misleading.

Depends how much you want to spend. Cheapest are simple code readers (adequate for your current issue) for around £20 right up to scantools such as AutoEnginuity at over £400.

All your codes seem to be related. Start with the simple things first. Did you wash your engine recently? The spark plug wells will hold water, causing a spark short or possibly crack the plugs. Get a new set and replace them since it has probably never been done before.
Send me an email to wm.c.unger@gmail.com and I will send you a complete Jaguar DTC guide in PDF format for engine, trans, climate control, ABS, SRS for your car. Without reading the OBDII codes and referencing a DTC guide, everything is just guess work ... and even then, it is not always easy!
Good luck ... Bill Unger

You'll need this:
DTC Summaries - V8 AJ26 Engine Management - 1997.pdf
But you'll need a minimum of 10 posts before you can download it.
