On my '87 320i automatic there are a two cables on the throttle, I get the accelerator cable and it's stop screw but the other one seems to be connected to the auto box and I can't find a setting for it- Also what's the setting for the stop screw on the vacuum device that seems to stop stalling.
The other part that's a bit unknown is the attachment on the inlet above the rocker cover that has two pipe on it and a screw adjustment inside, After I replaced the breather pipe from rocker to throttle body I had to screw it almost right in to bring the tickover down.
Everyone has the right to reach the level of their own incompetence.
