This is on going problem. Three weeks ago engine kept dying and had an egr valve fitted which solved this. Then developed a mis fire in cylinder 2 and had a new coil fitted. Now having the above problem but not every time it is driven. It also had difficulty going up a hill in second gear which it normally does without a problem. Local garage and breakdown service computer does not show a problem. Engine management light came on with all these problems but problem not detected on computer.
