It's so easy. Take off the intake tubes and then there is one clip and four 10mm screws and that's it. One of the easiest things to do, just take a few pictures before u dismantle.

Yep super easy. I have a throttle body from my 02 4.6 if interested and you have a V8 X. I replaced with a Dinan unit a while back.

May I intervene? The throttle body on BMWs have two different potentiometers, one reading high to low and one reading low to high. This gives a redundant signal to the DME and takes away the chance of a bad signal without it being noticed. If the throttle body was going bad it would have a check engine light on with throttle plausibility faults stored.
The violent lurch forward when accelerating from a stop is one of the potential problems with older transmissions, and is usually it not downshifting to first until you are back on the gas causing a really sudden engagement. If you have made it 150,000 on the OEM tranny without having any work done to it you may be due for a rebuild soon... In my professional opinion unless you are having other problems related to it and/or have fault codes specifically for it the throttle body is not the problem. So if you still want to try a new throttle body at least get the dinan one so you will have something to show for it.
