My Rst is spitting out black smoke and coughing when ever it starts to get warm once it gets to running temp the whole car will cut out. It runs as normal when cold. Does anyone know how to solve this issue as i need to get my car back on the road.

 

Sounds like the same prob ive got with my fiesta bar the black smoke. Ive been told its more than likley the oil pick up from the sump gunked up and to clean it and the breathers . h. im doin it tomorrow so ill let u know how i get on . Ally

 

Overfuelling mate, thats why it's fine when cold (needs extra fuel for cold stat/running), black smoke is a dead gice away

Most random piece of advice I have ever heard! lol

 

yeh it does sound like overfueling check the fuel pressure regulator, it may even be the setup
