Hi,

So after a sudden drop in power and running really rough. I got my codes up and Cylinder 1 was misfiring. I suspected a coil or spark plug had gone, so to test the coils first, I reset the code changed the coil 1 with 3. The car still ran rough but now Cylinder 3 is misfiring, now I have the part which I consider faulty, I decided to try this 'faulty' coil on the cylinder 2. As I suspected, cylinder 2 then started to misfire whilst the other two cylinders ran fine.

I got a new coil but unfortunately this new coil isn't working. Which ever cylinder this new coil is on, it throws up the same error on whichever Cylinder the coil is on.

I've compared the two coil and the new one is like 5/6mm bigger than the old one, is it possible it isn't seating properly? Could I have a faulty one? or am I missing something here?

Thanks in advance for any help.
