We have changed the obvious, even swapping coils but the misfire stays on cylinder 2. New Coils, new plugs. Newish wires. Any other suggestions? Please let me know.

V40 is fussy with plugs

Old post I know but in case it helps anyone else. We had a problem where the car would misfire when accelerating under load. Ie when accelerating quickly. Had one Swedish car specialist look at it. They did a bunch of work that did not fix the problem. Another specialist could not work out what it was. Ended up taking it to the Volvo service people and they diagnosed it as incorrect spark plugs. Apparently the 2001 V40 is very fussy about its spark plugs and needs exactly the right ones. This fixed the problem.
