Running rough.
Ok it's not an impreza but my clio lol.
Sounds like it's on three cylinders. Engine note doesn't change if I take the lead off the coil pack from cylinder 4, but it does change if I disconnect the injector for cylinder 4. I just changed the injector for 4 'cos I assumed it was this based on tests yesterday, but no good. I have had a look at the plugs and they looked ok, but I suppose I should think about leads and maybe coil pack now, but I'm still confused about why the note doesn't change if I take the lead off the coil pack? It 'seems' there is combustion with fuel and no spark? HOW!?
Edit - Fixed.

If disconnecting the coil pack on cylinder 4 makes no change my money would be on that but I'd get someone to check the electrical pulse going into the coilpack and assuming there is one then whether or not it is causing a spark. You might be able to check it with a multimeter on tick over.
