well it doesnt cut out. also next to the inlet manifold there is an oval shaped thing? with a plug fitted into the top which actually isnt connected. when i do connect that it makes it rev up and down on its own. sorry about the oval thing but im unsure what it is, bronze in colour alluminium i think?

do you mean this pic is from 3dr cossie, but there should be one in 2wd too.
if you mean that, take that valve of, clean it up very good, oil it whit gun oil or something thin oil. put valve back in and connect the wire. now try again.
note. there are 2 sprigs in that valve. and you must measure the little nut in the valve, so you can put it back to same position and lock whit a bit of paint or threadlock or something similar.

Mine used to rev and idle at 3k when i had the idle valve plugged in, if i unplugged it it sat perfect just under 1k. I thought it was the valve that was no good, but when my engine was rebuilt i was told it was caused by a gasket (cant remember which, sorry) not the idle valve.
(I had cleaned it too and it made no difference) Soon as the new gasket was on it was fine again

you did put that connector on too? was the O-ring in good shape, in idle valve? is there air leakage, in your air inlet manifold? try to find out it by spraying starter spray or somethin similar, in in your inlet manifold. if there is change in behavior of your engine, there is an air leakage. maybe one of your air inlets seals is leaking.

There is also an air adjustment screw under the throttle you can give the engine more or less air at idle i think you need to give it some more air at idle.
But it could mean you also have to adjust the mixture at idle.

In my opinion it could be a number of things!
1) Air leak around inlet manifold/anywhere after throttle body
2) Idle Speed Control valve (as discussed above)
3) CO setting on the ECU has been messed around with (mine had a very similar problem and this was the cause, get it to a specialist as if it has been turned down to pass an MOT the car will run lean throughout the rev range and could melt!)
4) Another sensor has gone funky, could be coolant temperature sensor or throttle position sensor.
Most likely to be 1 2 or 3 in my opinion!
