I thought I had a misfire on cylinder no.2, but changing the coilpack made no difference, so I thought it might be a blocked injector. Went to get it checked today. The result was that I don't have a misfire! 
However, I have absolutely no compression in cylinder no. 2, and poor compression in another cylinder.
This means either a problem with valves, or a piston ring failure, or both! Likely repair costs are between £350 and £600. To top it off, I need new brakes too.
