Mmmm, i've sort of sorted it for the mo, more of a bodge really but it makes the car driveable. Ok, this is what I did:

Took off the throttle body and removed the flappy bit inside the air intake by removing the two screws, sprayed loads of TB cleaner and removed loads of gunk. put flappy bit back (sorry, don't know the name), still idling at 2000+. I noticed that when the ignition is off, the TB is completely closed, however, as soon as the ignition is switched on, you can see the flappy bit move and open a little bit. Took TB back off again and visually inspected it, saw there was a major gap in between wall of the air intake and the edge of the flappy bit, SO, took out the flappy bit and noticed it had the edge shaped specifically for the TB. I turned it upside down and put it back, this has now sorted the problem by restricting the amount of air the car can induce, the car still takes a few seconds to drop to 900rpm but it's livable. One thing I have noticed though but haven't had time for further investigation, before turning on the ignition, I disconnected the water temperature sensor, with the engine running, it idles Ok, as soon as I plug it in, the revs increase, not sure , may be a red herring.

Hope this helps.

So strange how you have to modify the TB in order for it to work as it should do. I'm no where near as advanced as extracting the TB and swapping butterfly thingy's around, and so i'm going to hope to god that the ECU sorts itself over time as im very short on money. If it hasnt in about 2 weeks, then ill ring out a mobile re-tuner fellow to reprogram my ECU to standard. I've also got a gut feeling, after reading somewhere, that my engine management system could have entered 'safe mode' or something of the like. Im guessing this because when i sprayed carb cleaner in my TB, there was a point where i must have sprayed too much in at one time and forced the car to stall; hence entering safe mode or whatever this emergency mode is.

Thanks for the reply
