Soysauce23 Posted May 7, 2009 Share Posted May 7, 2009 Here are some pics to a vacuum hose that is plugged with a screw. I just wanted to know what it is for and why the PO would plug it. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
jayzrocket Posted May 7, 2009 Share Posted May 7, 2009 I believe It has something to do with the automatic trans. Or the motor used to have an auto tranny behind. I did a swap to 5 spd once and Iv'e plugged that very line because of it. Quote Link to comment Share on other sites More sharing options...
luvmy280zxt Posted May 8, 2009 Share Posted May 8, 2009 Yep its from the auto tranny, i just swapped mine not to long ago and plugged that up also. Had to get a plug from ACE hardware! plug it up good or your RPM will drop. Mine did until i plugged it up good. Quote Link to comment Share on other sites More sharing options...
