I have problems starting my 1991 740 wagon when it is cold. It hesitates when start moving and then picks up speed and runs normally. After it warms up problems are not as bad. I was told to replace the Mass Air Flow sensor. I do not know the location or looks of this sensor. Could someone please help. Thanks.

you have a number of things to do, first thing is take off and clean your idle control valve spray into both the ports with carb or throttle cleaner,then clean the butterfly in your throttle spray into there with the same cleaner, then pour a radiator flush in your expansion bottle that will clean your water system and clean your cold start sensor , do that first .
