Hey what's up. I have a 2004 525i. The rpm's on the car tend to go up and down all the time. Currently there are no check engine lights on and I just fixed the p0411 problem that the car was having. When I'm driving sometimes it studders to pick up speed but if I depress the gas and press it again immediately it goes right back to normal. If I drive the car in DS mode I rarely ever feel it happen. I checked the fluid on the tranny and it was really low so we added accordingly. Anyone else have this problem happen and know how or what I can do to fix it? Any inputs would be greatly appreciated! Thanks
PS I take the car to a local Indy shop that specializes in bmw.

 

clean the throttle body and maf sensor? It worked for me.
