Bob,
Here are the explanations of the codes you're reporting:
They all point to a problem with ignition module 1 as it serves ignition coils A1, B2, B3 and A4.
Swop the plugs for the two modules on the firewall (the harnesses should be long enough) and see if the codes change to P1368 and P0352, P0353, P0355 and P0358.
If they do, it's the module. If not, then suspect a wiring or ECM fault.

A perfect example of leaking ECU capacitors in a 97. In the early year cars the ignition modules served separate sides and cyl 1,2,3,4 were on the right bank. Your ignition faults are for two on the right an two on the left, exactly the same as my 97. There are several companies the will test and refurbish the ECU. I used ASI, but that was many years ago, and others may have a better price and positive recommendations. Link:

97 ECM issues crop up here fairly frequently and it's a case of 'when' rather than 'if', however your car thinks that there is a problem with ignition module #1 (P1367). The other four reported codes are consistent with this.
Swopping the connectors to the two modules will confirm or refute the car's self-diagnosis for $0 and allow you time to source a replacement if necessary.
ASI seems to be the go-to place in the US, but there's no mention of the test/repair service they used to offer on the website. $1,400 is expensive for a repaired unit, but they are getting harder and harder to source since the 97 ECM is unique to the XK8. Unlike some of the later versions, there is no crossover from the X308.
edit: Removal isn't too much drama, but you may encounter some 'tamperproof' bolts holding the module housing lid:

It’s odd that ASI is so expensive $1400.00 regarding a rebuilt ECU since they keep your old unit. All you’re paying for is labor to repair it. Module Repair Pro repairs your unit for $149 with a warranty. Quite a disparity yet ASI is in line with the Rebuilt Throttle Body.🤔
michaelh- the early 4.0 engines had cylinders 1-4 on the A bank, 5-7 on B. Bob is reporting misfires on 1,4,6,7. Two cylinders from each bank, so not ignition module related. That being said, I did switch on my 97 and the misfires stayed on the same cylinders, confirming the ECU problem.
...showing module #1 serving 1 & 4 on 'A' bank, 2 & 3 on 'B' - or have I (literally) got my wires crossed?
I agree it's likely the ECM given the '97 track record - just seeking to eliminate the other possibility.

Update on ECU Repair
I had the shop remove my ECU and I shipped it to Module Repair Pro here in SoCal and it arrived the following day (today) upon receipt they sent me an e-mail confirmation. Late this afternoon I received another e-mail indicating it was shipping back to me this evening. Being a skeptical former NYer I immediately called and asked if there was an issue because it was turned around so quickly. I was told it was repaired so quickly because their workload was currently very light. My fingers are crossed and hopefully this will solve my driveability issues and I won’t have to replace Throttle Body. The repair was $149 plus $25 to ship w insurance. If it works it’s money we’ll spent as ASI wants $1400 for a rebuilt unit.
