tick over is fine and seems ok when just rev ..

idcv seems to work as it changes revs when ya plug and unplug...

but every time drive (still not finished so not "proper" driving if ya know what i mean) it stalls at every junction you come to??

is it possibly the throttle postion sensor?

 

possibly but it could still be a faulty idle control valve, just cus ya plug it an it changes the revs doesnt mean it is working correctly.

 

actually though i had a faulty idle control valve a couple of years ago, i took it off cleaned it up an it was fine after that, try it mate
