1.8TDCI MISFIRE

2006 Ford Focus • 70,000 miles

Car has a misfire from cold at about 2000 revs, only when cold, strats fine, had service and fuel filter was changed still no joy, almost feels like it is a fuel feed problem, you can drive the car for a mile stop, get out and when you get in it does not do it again, hope you can help, cheers john
