Definitely change the plugs and you might want to somehow check the ignition coils as those are also a relatively common problem. Clean the MAF. I doubt the fuel filter is the problem at 100k miles, but it's good maintenance sense to replace it now.

From my experience you will not get codes from fueling or small spark problems like old plugs, which are not things the ECU directly monitors. Those would be good things to do.

Also what is the status of your crankcase vent/seperator system?

I had a problem very similar to this and it turned out to be a vacuum leak due the hoses going to the ICV being completely melted. I should have taken pictures because it was amazing to me to see the condition of the hoses. I have an '01 X5 4.4. These hoses are easy to see if you remove the plastic engine cover and look towards the back. Hope this is helpful somewhat. By the way, my check engine light came on and went back off.

The diagnosis is in, they called it the throttle valve. I'm thinking what they mean is the throttle body. It was sticking which caused it to stall. Makes a lot of sense to me.

I now wonder if this is something that can be cleaned. I know in most cars they can be. But since I didn't want to tow it all the way back home, I just told them to order the part and replace it.

I hope this for sure takes care of the problem. My wife wanted to get rid of her X5 that she loves and I do to. Nothing compares to a BMW.
