I will recommend you to check the vacuum supply to shut off valve (there is no adjustment for the valve) Have you switch the
old gasket to new shut off valve or replace
with new gasket ? Use the vacuum tester to check vacuum at brake booster line (normal you should gat at less 16 in hg vac ) if not
check you vacuum pump or leak in the system..
I think leaks in the air condition system.
The power door lock on your vehicle is operat
by a electrical pump (in your trunk right next to spare tire)
Warning if you install the vacuum shut off valve incorrect will cause WOT it will over rev the engien....... in few minutes you can
say bye bye to it.
