Well the car has aggravated me properly for the first time today, left work this afternoon, slight hesitancy, joined motorway and then it gets a bit more frequent. Then comes the full miss fire then clears. Get close to home all fine and then it suddenly runs on 3 permanently, no fault codes no lights. Pull the leads and injectors and narrow it down to cylinder 2. So swap out the coil pack, still the same, swap out the leads for another set, still number 2. So go pick up a set of plugs and they are not too cheap for the correct ones, come home fit them..........
still the same, so that puts me down to injector fault or something more serious, though the fact it started doing it while going very slowly and lightly makes me think/hope its just the injector.
