I am having problems with my 02 1.6 focus with 82k on the clock its running really lumpy/rough and is lacking power when accelerating and under load and is using a good bit more fuel it is perfect sometimes but then will just go rough mainly after slowing down and trying to pick speed back up I am thinking it might be the coil pack or plugs and leads but when I serviced it about 4K ago they looked almost new only had the car for 7 months it also has a old induction filter on it I plan to replace it soon any advice or suggestions that will save me messing around trying to fix things that are the least likely problem
Many thanks
