Thanks ash,the light does go off on the dash so maby I could rule that out:/
Thanks tlag,I've had it code read & nothing came up,also I was told a crank sensor wouldn't show up on the codes!?
Ok I will check the earths when I get back.
I did change the spark plugs last week & thought maybe I had knocked or done somthing but it was running fine for a couple of days before I got this problem?
