Inevitable Missfire and Rough Idle

Theres a missfire on cylinder 1, I've changed the spark plugs and the coils (all 4) but still no change. It idles rough, enough for the car to vibrate.



When I first got the car, it started cutting out (stalling) I changed the (Butterly thingy, that controls the air lol) ICV? That fixed the stalling.



Theres lots of posts on this but so many different solutions...which means lotsa money if its not the cause.



Can someine list the most common causes and solutions please? I feel it would be better to have a list of "fixes" on one page as opposed to searching through all the posts



My car is a Renault Megane 1.4 2004 MK2



Thank you
