hi on friday i fitted some 330cc injectors all weekend its been fine but i was driving home from work came up to a junction and it cut out it drives fine but when i stop it cuts out. do you think there is any link between the 2 or a sensor has gone? also opend the oil filler cap and in the top of it was milky only a little bit of it in the top the rest of the oil seems fine and so dose the collant it hasnt lost any coolant either that i can see i was told that some times u get that in the cap is this true or am i beeing paranoid or could it be the headgasket? thanks
