throttle body port

[john jackson]

I am finishing up my install and have nipple on the side of the neck where the throttle body mounts and can not remember where it goes. It is opposite the egr valve. If any body can help me with some detailed info on the vacuum routing it would be greatly appreciated. This has been an eight month project on a 88 cavalier that is finally almost done!

I would guess the trans modulator on the front of the trany if its an auto. It's in line with the starter.

If your talking about the one in this pic, then yes that is the line that goes to the vacuum modulator on the front of the tranny.

Perfect place for a BOV vacuum line if you have a 5-speed!! :wink:

redt! what did you clean your upper intake manifold with?

It looks cleaner in that pic cause of the flash and angle of the camera. But it is alot cleaner than most I've seen. I used a wire wheel in my dremel. then I got the engine degreased with citrus cleaner. After that I repainted around the 3.1 Intercooled Turbo. Then I took a sanding block and went across the top of the plenum.
