Hello, I been having a read around the subject but thought I’d ask as well. 54 plate I.4 pertol starts lovely every time but will just cut out whilst driving, ok on a country lane but bloody scary on the motor way. Just a quick on and off again and it’s all back up and running, sometime for a few days or 20min. I havnt looked at codes yet as my mate is on holiday but some of the threads mention voltage drop to the ECU caused by doggy earths. Can somebody pint me in the direction of them. Any help appropriated thanks Jim.
