I have an 07 1.8 FOCUS zetec and the engine has a slight misfire/hesitation at low revs, it usually happens in second gear when you put your foot down, its very slight but definatley happening, its also more pronounced when the AIRCON is on, I will be taking it back to the dealers, but will this show up when the plug it into the COMPUTER thingy, and Does anyone have any similar experiences of the 1.8 engine or reporting a misfire, My worry is that they will take it in and not be able to find anything, and i dont want to have to keep taking it back over and over again for them to say theres nothing wrong etc etc.............? because as we all know MOST FORD dealers arnt the most accomodating of people, especially when the have got your money!!!!
