Hi all,
Thanks to all on this site that have made owning my X5 more enjoyable. I hope someone will be able to give some advice on some occasional vibration I have been recently experiencing when slowly accelerating while driving slowly. I have had the vehicle minor serviced recently with no error codes present at the time of service. I notice that when the engine is warm and while in park, if I press the accelerator slightly and hold it the engine revs climbs and drops repeatedly about 200-300rpm. Though it may be due to a dirty MAF but when disconnected the engine does the same. Has anyone experienced this or know what could be causing this. Engine starts well when cold and accelerates good under heavier acceleration, fuel economy seems lower but may be due to me accelerating faster to avoid the slow acceleration vibrations. Is there anything I can try to see what may be causing this? My X is a 2003 4.4 Sport.
