Hi guys,

Been getting a few probs with my car, it was idling incorrectly, but has now been rectified by changing the idle air control valve. Now however, whenever I brake and change gear (mainly into 2nd, say coming up to a roundabout or junction) the revs drop to 0 and the car stalls unless I quickly press the accelerator to get the revs up again.

It also 'hops' a little when accelerating, but then runs very smoothly, until that dreaded gear change! It stalled on a roundabout earlier as I had some idiot pull out in front of me and I had to change gear quickly which it didn't like!

I have no idea what could be causing this, the engine now idles when stationary at 1000 RPM (whereas before I changed the valve it was idling between just above 0 and 1500rpm!), Is 1000 RPM normal idle speed for this car?

I am thinking of taking it in to be put onto a diagnostic machine, but obviously this costs a fair bit of money so thought I would try here first! Thanks in advance!
