Idle air control valve maybe? However with this you should sometimes get a higher idle. Quick solution is to open and clean it, better solution is to replace it.

Also are your spark plugs fine? Totally wrong spark plugs can also cause similar symptoms.

its either your idle air control valve or your crank position sensor, more likely the idle control valve iirc

i did forget to mention it idles about 1000rpm wouldnt it cause lumpy or rough idle then? just cuts out lol how do i clean it out whats the best way? cheers guys

If the ECU detects that the IACV is totally off, you will get a rough idle at about 2k RPM (very nice sounding BTW, like a rally car). To clean it, just remove the air hose and electric connector to it (and the coolant pipes I think). I have no access to carb cleaner so I just gave the parts a good wash in petrol. The parts you will need to clean are the housing, a small filter like thing and the rotating cylinder. You will see those when you open the IACV.

However the improvement was only temporary for me and eventually I fitted another IACV.
