   We are having a bit of trouble with my girlfriends Y-reg VTR. The engine light is coming on regularly, sometimes it hunts when idle, occasionally it misses like it's down on one cylinder.
   
   We have taken it to an autoelectrician and retrieved the fault codes as follows:
   
   P0300 - Cylinder missfire
   P0301 - Cylinder 1 missfire
   P0302 - Cylinder 2 missfire
   
   Since then I have replaced the spark plugs (with new), and tried 2 other coil packs (second hand). But the same fault codes and problems are present!
   
   Any ideas what I can try next?

   misfiring can be caused by so many silly things

   I've tried 2 other coil packs (second hand), but the same problem with each. Is it likely they all could be faulty?

   I'll try some injectors then, and let you know how I get on.

    you could always take the injectors out an check if there actually injecting petrol
