Or bad connection?
I have noticed that when I take the ECU out of it's box (with the engine running) and move it into different positions, the engine revs go up to about 2,000rpm - but settle when I put the ECU back to it's home.
Any ideas?

which one , LPG ?

Nope the main petrol ECU.
There is no LPG on this car :y

its something neither I have courage to nor let somebody try :-[

I guess the answer for this question is related to electrics entering Kevin Woods area..
-
ECU's shouldnt be moved about when there working. if it works OK in its proper postion leave it alone or you will regret it :-X
-
Like my Gp said, when i told him my arm hurts when i move it about, "dont move it about then"
He was not very helpfull either, nor did he tell me why it was playing up.
Why you wiggling it James?

Apart from the obvious dodgy connection....a dodgy connection?!
-
I'm intrigued as to how/why you discovered this ... ?? :)
What reason is there for removing the ECU whilst the engine is running ???
Pray tell .. ;D ;D ;D ;D

Seriously there's an occasion ..No ideas ?

Sounds like a dodgy connection to me. Did it pick up any trouble codes in the process? It shouldn't affect it in the slightest.

lol, sounds more like wiring or the connector.......remember that when moving an ECU its not like your actually straining the electronics!

Don't you realise he made the main chip go dizzy! ;D

Any idea which wire in specific I should look for Mark? Maybe an ICV one or something? :D
I removed the ECU earlier in order to inspect for dodgey wiring, when looking at my Lambda issue, for all you curious people :y

Think your trying to compete with Tim.
-
Sorry I didnt explain my self better. The wires are dressed which means they are of different lengths so when you wagle the ECU about you are stressing the shorter wires and this can lead to a breakdown in comunication,hence the car may see a fault and go into limp mode.So as I said if it work leave it alone

The point is, it doesn't work. ;)
If something is getting disturbed it indicates an intermittent connection and this might be related to the Lambda sensor fault.
Might be worth unplugging the ECU and checking the connector is clean. Also check any other connectors between ECU and Lambdas. (IIRC) there's another multiway connector between engine and body looms.
Taking the engine loom out of the cable trays and inspecting for damage might be worthwhile.
Difficult to say what caused the fast idle. IACV may have been opened by a duff connection but could equally be that the ECU saw and intermittent signal and opened the IACV to prevent a stall.
A peek at the live data while waggling things might show something. :-/
