If anyone can help me it would be much appreciated! I have an 04 (march) megane 1.9dci and when I start the engine it idles very roughly and also when I accelerate to change gears it judders quite a lot and then when in 5th gear, if I put my foot down to speed up it judders as well. It doesn't lose power. I have no idea about engines, only the basics! So if anyone could help guide me as to what it could possibly be I would be so grateful
