I have to add some more information. When the engine is running, I can
unplug both the hall sensor and the flywheel TDC sensor without
difference. The only sensor needed for the engine to run is the
flywheel RPM sensor, but it needs all 3 to start.

Checking the Bentley wiring diagrams, it appears that the tachometer
is connected to the ECU.

Is it possible for the distributor to become loose and move so much
that the ignition timing gets screwed up? It does not seem loose now.

Another strange thing is that the cars runs just as good as it used to
over 2000 rpms, it's just hard to start, runs bad on low rpms and with
a non-working tachometer.

I pulled the codes again today, no faults recorded (4444)..
