Okay guys, I was out testing the X5 out after installing the new VW MAF and seemed to be fine until I came to a full stop. Funny how one problem is almost resolved and new one appears. So, now that the jerkiness/hesitation has cut down tremendously I noticed that I am getting a kick in the rear when the vehicle gears down to first when coming to a complete stop. The L/100kms needle also fluctuates. I didnt have this before the install of the MAF and reading some old posts suggest cleaning the throttle body and fuel injectors. The messed up thing is that I dont get any hesitation or kicks at all when in Manual mode or even in sport mode, not a single glitch. The X5 seems to be better on gas in Sport mode, that cant be right. I am so puzzled by this vehicle its driving me nuts. I initially thought it was the tranny and now the puzzle seems to have gotten larger. The good part of all this is that it seems not to be the tranny. Anybody have any suggestions on what the problem it could be?
