Hi folks
My daughter's Mondeo used to start first turn of the key every time ,but lately it has to been turned over quite a lot to get it started ,then its with a puff of black smoke and a strong smell of petrol,checked the air filter but it was pretty clean ,took the plugs out and replaced them ,checked them again a couple of days later to find them sooted up ,she also says it is using more petrol than it used too, so i guess its something to do with the mixture or something along those lines ,its a 51 plate 2.0 ltr ,thanks in advance for any advice ,Steve
