Check Engine Soon :( - ZR-1 Net Registry Forums

You can "rebuild" the vacuum harness by simply changing the check valve out- the valve is a generic part that you can buy at NAPA. Also, if you are lucky you can install the same check valve where the vacuum line goes into the plenum on the drivers side. It will act the same as the valve that's bad in the harness.

Disconnect that hose, plug it and then apply the vacuum to see if it leaks. If it holds your little check valve is bad- easy fix.

Write if you need additional info- I have done this before.

P.S. Check this shyt out... just got a quote from a local dealer.... UGH... And the vacuum harness isnt even listed there because GM doesnt make it anymore. Im gonna use burger king straws and duck tape for my new vacuum harness. If you cant Duck it,... FVCK IT!!
