Vacuum Question
I have a 91 Z28 I need help with on the vacuum lines.
On the passenger side of the plenum in the back there are 2 vacuum fittings and a sensor. What all goes where?

Are you talking about the sensor by the ignition coil? That is the egr solenoid, a line from the front of the throttle body goes to one fitting and one from the egr valve goes to the other one. There should be a label on the inside of the hood over your right shoulder as you're looking at the engine. That is your vacuum line schematic.

I figured it out.
My problem was I didn't realize the Map sensor plugged into the plenum too, so I thought that I had 2 missing lines somewhere. I was also making sure the FPR went into the plenum.
I had the EGR hooked up correctly.
