Anyone had expirence of Vauxhall Astra 1600 8v's running erratic & often stalling after 5-10 min of running (from cold). No fault codes stored, actual data looks to be all correct, fuel pressure does not drop and when the vehicle is running rough the mixture is weak - indicating fuel rather than ignition. Also checked voltages,resistances & Earth's to sensors & ECU. Suspect ECU?
