Has anyone had experience of a faulty injector or injector loom on here? Or knows what is more commonly at fault. Ive narrowed my misfire down to either of the 2, but now its trial and error, i've bought a new loom to try, and if that doesnt cure it then a new injector. Also, anyone know how easy the injectors are too fit? I know its easy to fit, but a mate of mine said to be careful as sometimes they need proper setting up with a computer?
