I have the entire throttle body assembly (TB, Sensors, etc)that I took off of our 1999 E22 if anybody needs one for parts. The ETCS motor was not working, but I believe the rest of the parts work. I will let it go for cheap if somebody needs a part or two off of it.
$75 plus shipping and if it doesnt work for what you need then ship it back and I will refund you.
