OK, quick update.
Junction box sealed, car has now driven further than it has before without breaking down.
However, it is not raining (for a change).
There were 2 streams of water coming in, one across the foot rest, and one onto the pedal. The water was coming through the junction box, running down the outside of the cable and onto the pedal.
So, I would add this to the list of potential problems and fixes:
1) check, no CLEAN all grounding points. In particular the one near the ecu and underneath the battery.
2) Change all vacuum pipes, especially the one going to the ecu and also the litle one inside the ecu.
3) while it is out, clean the pins on the ecu irrespective of how good they look. Silcone Grease ie CAGE mod is a good idea
4) Check or change both brake switches.
5) Check for water ingress through cable junction box on to accelerator pedal.
6) Change the throttle sensor if none of the above fixes.
I'm not going to say it's fixed until it performs the same way when it's raining. But, the long drive has shown that it's not a heat related issue.
I'll update when/if that happens.
I hope this helps anyone else with this infuriating problem.
