Help Remove Throttle Body Housing

[Dreamer52]

I've searched but can't seem to find any help in removing my '89 911 throttle body housing. I need to replace the throttle posn switch and don't even want to try to mess with the switch while still installed in the car if possible, seems to be no room to get to the bottom screw. Anyone done this or point me to some documentation?

Thx

You should be able to access the screws fairly easily with the airbox and AFM removed.

Thx, I'll give a try & report back.
