All properly running gasoline engines have a normal vacume reading of about 17 to 22 inches, but more critical is whether or not the vacume is steady or not. The difference in those numbers can still be normal for your engine, and doesn't nessecarily mean malfunction of the engine. There can be many things that are causing low vacume, such as leaking gaskets, leaking valves, ignition timing. When you do get abnormally low vacume, the cause can be identified with other methods. This is with the engine warmed up to operating temperature and idling at its proper speed. There should never be flickering or varying of the needle when it is running with out any interference such as working the accelerator linkages. If the is any of that kind of activity with the gauge's needle, it would point to the need to check for actual problems with other instruments, and logical analysis. Vacume diagnostics by it self is not a conformation of malfunctions, but simply part of an overal analysis using other equipment and putting the engine through different conditions while running, such as reving the engine up erratically and continually watching the needle. watching how much and how quickly the gauge returns to normal after doing some of these things, especially that of snapping the throtle open or closed and knowing what to expect while doing so. There are many different needle reading, such as; low and steady, low and fluctuating, regular fluctuations, irregular fuctuations, rapid fluctuations, slow fluctuations. Intermittant drops then rising to normal, large fluctuations,
