So it seems I have several things to do and check:
engine bay heat
fuel pressure
ignition coil pack
And one other, though remote, is the ECU. It is housed under a baking
pan in the rear bench seat storage. Adding a few vent holes to the pan
couldn't hurt.
(he admits sheepishly as Mark Drillock and I salvaged a VSS from the
junk yard):
I do have a Mk2 (or Mk3 ?) VSS for the speedo. There has been no rev
limiting issues that are generally associated with a missing or dead
VSS but maybe installing it will correct the idle hunt, engine up to
temp.
The wires to ECT have been checked many times. I had to shunt in new
wires (these can be had with the female spades already installed) into
the ECT connector at one point. All connections soldered shrink
wrapped etc.
It's something. I will find it.
Neil.
