Hi Guys, A couple of weeks ago I had a problem with my car stuttering at 50mph for about 10 second, then all fine. Glow plug light flashing. so checked the maf and cleaned (if you remember there was a gap at the side of the maf, which should not be there. Due to wrong filter housing. changed the injector wiring loom about 9 days ago. Also cleaned the control flap as it seemed to be sticking and ordered a new one. Still waiting for it to be delivered. As well as a new fuel filter. So after doing the above the car was still shuddering at 50 mph. Until 5 days ago. Started the car as usual, Low and behold no stuttering. 5 days on car still running fine. Touch wood. So my question is. Is it possible the car took time to realize it has a new wiring loom. Then rectified itself. Or is this a myth. Also should I still go ahead and change the flap. the car is running like a dream. or should I leave it well alone and see how it goes.
