Servus together, I’ve had a severe problem with my RS engine and though, I’ve got on the engine 19000km and it’s already 6 times the pins, cords, coils have been changed. So the problem I have is the following, if it’s cold then it’s not running properly round,that’s called stuttering like sow.But that’s what it does when it’s warm.It’s undriving when you drive it under 2750 turns it’s running well again.What can that be? If I clean up new spark plugs it’s gone for a couple of days weeks,then I have the same problem again.Who can help me? nor what can I please not drive to your Ford dealer, if the car is more with my dealer than with me.Hat of you who the same problem and above all what can be done against it.
