My Corsa 1.4 16v auto 1999 keeps cutting out when idle e.g. at traffic lights and junctions. It starts first time. Have had the idle control valve and lamda sensor replaced and it still does it. The revs go up and down when idle but this does not happen all the time. Help please!
all these symptoms are pointing at the idle control valve which could be faulty. also check all engine breater pipes are clear and also try disconecting the battery for 10mins once reconnected drive for 15 mins as the ecu may need to relearn its settings for the new idle control valve
