Hi guys, in my uk vitara (16v) (kick/tracker) it has started to cut out when im in nuetral at juntions, or when i am rolling up to a junction.  the revs just go really low and then it cuts out.  it doesnt always happen, but it happened a couple of times recently, i am right in thinking it might be something to do with the air sensor or something.
any thoughts
Cheers guys.
