Last time I ask for help on this issue... trans shifts?

Are you still running two fuel regulators?
I know you just replaced the B-bank unit (I think) but do you still have the inlet (A-bank) regulator in place?
If so, bypass it and see if anything changes
Long story short I had a terrible bucking/cutting out problem with my '88 XJS and it was the inlet regulator that had failed

Bypassing the inlet regulator.....
Note item #10 and #1 in this illustration:
https://parts.jaguarlandroverclassic.../brand/jaguar/
Eliminate item #1 by simply disconnecting it from the fuel inlet pipe and the inlet regulator
Run a new hose from the inlet pipe directly to item #10. The #10 pipe has a knob at the end that you can slip your new over and secure with a clamp
3/8" ID hose as I recall

Looks like you have been chasing this for a little while - was going back through the forums chasing other stuff and found some of your previous posts
July 2017 looks like you had water in your fuel system - left overs from when you did your fuel tank?
August 2017 very dirty fuel from your sump tank.
January 2018 - having similar issues to what you are having now - so the title of this thread makes more sense to me now, also when you changed from 2 coils to 1
Interesting to read the XJS rev limiter thread #33 https://www.jaguarforums.com/forum/x...-153911/page2/ saying he found and fixed his issue
I am understanding your frustration just that little bit more
Cheers

Alright I’m in a positive place now. I did remove the inlet fpr that didn’t do anything... then I was sitting with it running and just looking around. I started revving it with the cap stand and opened it wide and it started idling funny, up and down. that was new... so I for whatever reason pushed the fuel enrichment switch and the car almost quit. Then it went back to idling weird. So I clicked it again and held it. It revved up and down faster. So I got in the car and revved it trying not to hit the enrichment switch and seemed like it slowly revved past 5k... then I mashed the throttle and instantly cut to the rev limiter feeling back at 5k. I’m thinking the fuel enrichment switch is junk!
