Vectra(N) 1.8 cutting out..idle speed valve

[Isildur]

Looking for advice here, the car will stall when slowing, or at junctions etc, we hooked it up to a diagnostic system and it was fine, so the garage said it was the idle speed valve and said to replace it (£200) However i found a page.. http://thunderace.legend.co.uk/cgi-bin/advice/index.pl?read=4623

And it says i'm better off cleaning the valve and the pipes, then fitting a 'flame trap' to stop the gunk getting through. So basically buying a brand new valve may stop the problem temporarily, but the real reason for it would remain.

So you'd advise me to replace it brand new (i would do this if i knew it'd solve the problem for a couple of years)

Or is cleaning it sufficient?

no what i meant was i did as what was on the website
cleaned it not replaced it.

WD40 works fine, used a brush also
