take a look at the distributor post

i've had similar cause/symptoms with my XJ when it went out...

What i think happened:
when you down shifted, the engine RPM's raised the RPM's faster than the distributor would rotate, and this snapped the shaft inside that connects the gear on the cam, to the distributor rotator...

Whats happening now:
since its broken, when theres "excessive load" it separates the two pieces of the shaft, it goes on the frits from the other cylinders misfiring out of time...

you might need a strong magnet on a wire to get the broken part out, depends on how/where it broke. (it shouldn't go anywhere when you take it out, mine didn't) no promises

hope this really narrows down the search for ya
