My wife's Amica had a misfire, mainly on cyl 3, and after replacing the usuals I eventually tracked it down to blocked injector filters. The rail and injectors are easy to remove, and the filters can be wiggled out with a flat-ended no.10 screw and pliers. The filters can then be cleaned with Redex or WD40. Worked a treat. No.3 was almost completely blocked then no.2 started throwing up an error too so I cleaned them all out. No problems since.
