   Faulty injector? Does it sound like it's running on three cylinder's? Injector's on these are SOO easy to change..

   Get it hooked up to a diagnostics machine before you spend any more money mate.

   TBF i would go and have a compression test done and see if the HG or valves/seals are knackered, Could be losing compression from them. Then if the compression test is good, Take the injector rail off remove injectors from the rail and test them with a multimeter to see if they are all working..
   Thats the only main things it could be. I cant see a dodgy sensor that would make it run like a bag of nail's

   2 other options change the fuel filter and/or get the injectors proffessionally cleaned.Compression test is also a good idea.

   As Steve says.. But i would get them checked 1st to see if one's not died. OR it could be HG losing compression through the cylinders.
   If it was me i would have the compression test done 1st.. I only pay £5 so it aint tooo much to do in other garage's..
