Should take about 3 or 4 hrs. Took me 4 days, got stuck and had to wait for parts. If you have a 1999 build pm me and Ill send you the link on how to disconnect/connected the throttle body harness, its this twist plug you have to set and lock. I didnt understand it, a simple clip would have done the trick lol bmw...
