!997 VW GTI 2 Litre 8 Valve keeps cutting out when tickover revs of 950 drop suddenly, at say traffic lights or junction, to 450 and stalls.In an 8 mile drive it cut out 3 times.A little while ago I part replaced the ECU.
Does anyone think it could be the ECU again or have you any other ideas please
