the last few times ive started the car up it seemed to rev itself up every now and then until it was properly warmed up then it would be fine ...

So today i took out the Idle control valve and sprayed it with wd40 incase it was 'sticking'
Took the car for a 20 mile drive to dust off the cobwebs and again it revved itself up occasionally, the first 10 mins of driving the car were very rough.
Under normal driving the car would stutter as if it was running out of fuel but if you dropped it down a gear and thrashed it then it was fine

After 10 mins it seemed to pull itself together so finished the rest of the journey without any problems


I thought it was the ICV but now im stuck, any ideas?
