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