I recently purchased a 1987 nissan d21 pickup 2.4L, the engine was shot so I rebuilt it. The problem im having is that when I received the vehicle all the vacuum lines were a mess and most of them missing or disconnected. I have looked everywhere for a detailed vacuum diagram for this vehicle and have not yet been able to find it. I was hoping you guys could help. Thanks, Dyerpunk

I'm looking for a diagram of the vacuum lines for this engine. Upon inspection, some vacuum lines are attached and some are'nt. Do you have such a diagram? Right now the engine does not idle smoothly. It goes to fast idle to almost dyng but manages to keep running. Thank you for your help!
