The one way valve on the breather system was being a 2 way valve and not
closing as it should at idle.
So the breather system was sucking air through into the inlet manifold
at idle and generally confusing the ecu.
The servo also has a vacuum leak.

Hi, what was the issue then, breather/intake leak or pressurisation?

Jim and Steve,
Thank you both very much for your help on Saturday, the 2+2 already
runs a little better after the alterations to the crankcase breather
system. Tick over is now down to around 1400rpm, so better than was,
I hope to replace the brake servo tomorrow and with luck it will
bring the revs down to an acceptable level at idle, I will post
tomorrow evening with the results providing I can obtain a new servo.
Geoff.

Not disconnect it, leave it connected but unbolted from the
throttle body so it's always at it's lowest setting.

Ahh yes, that the thing I just tried disconnecting while ti was
running and it made no difference. See previous post (they all
seem to be getting a bit out of order!).

The black module bolted on to the other end of throttle
spindle to the linkage.
Has a 3 pin connector on it.
Otherwise known as the throttle position sensor.

Do you mean remove the throttle body from the manifold?

It's possible, remove it and see if it then hits
the stop, also try running the engine with the
throttle pot removed from the body but still
plugged in.

Could the sensor its self be stopping the
butterfly from returning to closed, once the
engine has done anything more than tick over?
