I've had my n/a 1988 rx7 for almost a year now with ups and downs but I'm starting to notice areas that have palces for vaccum one on the motor and another over by my oil filter that goes up to my throttle.

I will try to get some pictures up lateer on when day time comes but where do i connect my pressure sensor? I can't find a place for it does it go on the intake?

Q&A welcome just need to learn some more avout how vaccum and air works still

Not sure what U are asking for? You are looking for vacuum lines?

mrblackdog

What I'm asking what goes into the vaccum ports there is one on the engine. that when covered up drops my rpms to 3-500 rpms and the other vaccum line I'm curious about is the vaccum line that comes off my throttle it has a spare line that goes out i hooked up a vaccum gauge to them both the engine is very healthy but they have no tubes hooked up to them. and as for my pressure sensor where does that hook up too?

mrblackdog

This first one is on the right side of the car near the air intake and just right above the exaust manifold.



this one is by the oil filter and is part of the throttle what do these to vaccum spots hook up to?

1st pic runs to the Pressure Sensor. 2nd pic runs to a contraption that is connected to the oil filler neck.

mrblackdog

ok thats good to know but why is it that when I cover up the one for the pressure sensor I start idling at 500 rpms after I make a start up?

Are you leaving the other line opened? There could be other causes for this, but the first pic most definitely runs to the Pressure Sensor.

yeah the otherside is staying open tryng to find it since last night but im kinda not feeling to healthy today to find it.
