Cylinder 2 missfire

Hi Folks
I hope yous can help me here as I'm a Newbie to the site and Alfas.

I have a 156 jts which has developed a missfire on cyl 2, the reader showed codes for a missfire and cat out of range.

I have tried a new coil but no joy, I pulled the spark plug out and it was soaked in fuel but it does spark when dry.

Is it a faulty injector and how hard are they to change with the head in place, as it took a bit of time to disconnect the plug to it to stop fuel entering the cylinder as i had to get home and didnt want to damage the cat.
Any help would be great.

From what I have read on here they are difficult to get at a bit of a pain .
They are also problematic due to them using the same injectors as the standard twinspark.
This makes them more prone to failure as they are used direct injection .
Make sure you check and clean the connections as well but sounds like the injector maybe the problem .
