I did the test and got 18.5 in/hg of vacuum. Seems thats correct considering thats what it measured right from the vacuum hose as well. So it seems there are no restrictions. No gas coming from FPR at idle with hose disconnected. Any other thoughts for the 1123 1125 codes. It seems only to come up if I accidentally get close to stalling the car w the clutch or I rev high briefly getting into gear. Although the code is still pending shortly after reset. V

Have you done an intake vacuum test????
If you get 18.5 in of vacuum that is within spec but on the low end.
I had a minor vacuum leak on my 2000S and still pulled 19.
If you have a vacuum leak it could contribute to your codes.
