Vacuum pipe
Can someone tell me what this black pipe connects to.Just changed injectors and i remember seeing it under the plenum but can't see anything to connect it to.It comes from what looks like a ported switch at rear of engine,passenger side.
Car runs fine with it not connected.I remember the end of it being near throttle body.
