2000 Chevy Malibu 6 cyl Front Wheel Drive Automatic 102000 miles
I replaced the intake manifold (lower gaskets). Everything is workding fine except-
during reassembly I was unable to locate the vacuum line that hooks to the upper intake plennum right by the fuel pressure regulator.
After some searching I found the broken off end of the line in the engine compartment.
I cannot find the rest of the line or any unused vacuum port anywhere.
there is no vacuum diag. Anywhere on the car or in my Haynes repair manual.
My gas milage is poor. No engine trouble codes are being set.
