My BF does exactly the same, and always has. With the dual fuel (Orbital Liquid) system and modified exhaust the same issue seems to have become more prominent. If only Ford would have a fix for this because, AFAIK we are powerless to do anything about it. I don't even think it is possible to fix it with a tune. Then again, I may be wrong. Good to hear I am not the only one. It seems to me the car is dumping loads of fuel into the engine at start up (unburnt fuel smell) to the point where the engine cannot run properly. Annoying problem - doesn't give Ford a very good name either.
