Hello there, bought the missus an Astra G 1.6 8v 2001 a few months\nago\n& it has started loosing all revs on a few occasions when coming to a\nstandstill from a run eg. when stopping at a roundabout or junction\nafter a trip down the by-pass at constant speed/revs (around town it\nseems OK). My guess is the idle control unit may be sticking & needs\ncleaning or replacing. Could anyone tell me where to look for this\nunit under the bonnet & if anyone else out there has had the same\nsort\nof experience was it this or another cause. Thanks, Mark.
