Hi there,
In reading over the posts from others I see a common thread with Arts possible power problem being very likely.
You spoke of the speedometer needle doing the bounce thing.
That usually can be seen with these electronic speedometers when they are first fired up on the ignition key.
I think the incoming power spikes the circuit and have seen the needle bounce.
Now how the brake pedal can do this. I don't know but if there is a bad connection or low power coming in on the system, the brake lights load might weaken the input to the speedometer.
I admit my thoughts seems far fetched though.
The ECU diagnostics and the ECU using a speedometer output, somewhere close to or in the 90's cars, this could cause strange responses, besides removing the memories.
I like the idea of the two prong fuse block for this and the wire from the battery to the junction block on the fender.
About the engine running with stink and drop in mileage, I want to suspect the Engine Coolant Sensors input to the ECU. A bad FPR is also a good suspect for excess for this as well.
One might learn a lot by taking a good look at the ECU connection.
Probe pins inside it for power input voltage drop and the resistances range from the ECS.
The static discharge from the body to the car is usually a clothing preference.
Sliding against some Wool or some polymer cloths can cause electrical discharges.
Using Shepherd or Plastic seat covers and adding in some medium dry hot weather helps and cold dry mornings temperatures can cause sparks.
Good luck and keep us posted. You symptoms on the car are interesting.
