Just shows you that our doctors did not go more as they did 200 years ago. Bloody highly paid mechanics they are!
All the best to you Dave!
By the way I have same sort of a problem with my truck here mechanic said it is because COMPUTER do not know how much petrol it should send to engine(what a heap of crap!) And I had to pay 3.5K for this...
They did changed the motor by invoice....
Smile anyway
