Another update:

Pump is whiring in second click key position.
Earths appear intact.

Have now again taken the airfilter hose off and trying to watch the butterfly behaviour.

Appears to be completely shut at start-up, even though the throttle actuator is whiring and holds lock to the butterfly.

When idling, it still looks prety closed to me, until pressing the accelerator pedal where it seems to opperate fine.

Engine runs fine, plenty of power etc. appart from slight jolt of power sometimes when pressing the pedal.

Eh?

Checked the throttle position sensor?

I think that is inside the actuator unit, not like an external pot as usual.

What do you suggest to check?

- SOLVED -

ECU update to the latest version needed due to bad software version from a previous update on 14/9/2007.

For reference this is before:
(note sometimes it would not fire-up at all when completely cold and needed 2-3 goes).

After the update of ECU (flash programing):
s875.photobucket.com/a...V01466.mp4

This is now confirmed and the overall performance of the engine is much improved.
The 'jolts' when pressing accelerator if cold are completely gone. Smoother throughout the rev range.
No loss of power compared to before.
Much quieter engine (thought it had stalled on idle a couple of times).
Ever so slightly lower engine temp.

Thank you Lee for coming up with this:

The chap on PP2000 at Peugeot dealership also gave me this:

Which I translated btw.
Cost 50 EUR all in.
Mine is up next I think.

Cheers everyone. Very Happy

It's been great help to hear from all of you! The car runs smoothly and starts every time. All your input is appreciated!
