Has anyone had any problems with a leaky fuel injector for an X3 2004? If so, how is it caused and how much would did it cost to have it repaired? Is this common for the X3? The car has problems starting; the dealer said it wasn't the spark plugs. When its cold, it has problems starting but when its warm it starts up with no problems. Help! Has anyone had their cars serviced by Bovarian Imports off of Howell Mill Road in Atlanta, GA? If so, please give me some feedback about your experience. Thanks.
