Engine shuts off while crossing intersection!!!

[kneedragger]

I own a 2002 4.6iS and when driving home tonight I was making a left across an intersection and my engine cut off. I tried repeatedly to get the car out of the road, but it kept dying a few seconds after I turned the ignition. I then revved the engine to about 3500 rpm and put it in drive and that allowed me to pull over into a parking lot. The engine was idling close to 0 on the tach, but I was able to make it home okay, which was only half a mile.

Any idea why the X5 is doing this? Something similar happened a couple weeks ago... I came to an intersection and the light turned yellow. I hit my brakes pretty hard and when I stopped the battery light came on like it does when the ignition is on "accessory mode", the car lurched like it was about to stall, and then came back to normal throttle. This was on my way to the BMW dealership for service on the radio volume cutting out. The dealership couldn't find anything wrong with the car.

Any help would be helpful. Obviously I will be taking the damn X5 back to the dealership and I am even considering having road side service come out and pick it up. I could have gotten into a bad accident if traffic was heaving on the street I was crossing.

Sounds like you have air leak!Look for any loose vacuum pipes including those on your sensors!Also check on the sensors for wires that may have disconnected or become loose.Check your MAF for loose wires also.You will find your Maf on the tube coming from your air-fliter box.

or maybe the fuel pump?

Seems like a loose vacuum hose. Have the dealer look at it...

Looking at older threads indicates that this was the result of bad ignition coils. Kevin had this problem too. I think that what it turned out to be for him also.

check ur battery terminals? if the battery light comes on, wouldn't that suggest a possible loose cable?

Sounds like the intake tube has come loose from the throttle assembly.
