Vacuum Gauge Not Steady. If the cranking speed is normal or high but vacuum is low and slightly uneven, the engine probably has low compression or retarded valve timing. This indicates that the engine has a leak in. General ignition issues or sticky valves. A quick opening and closing of the throttle should cause the vacuum to drop below 5″ then rebound to 21″, or more. a high, steady vacuum reading is the sign of a healthy engine. If you're at altitude, these readings may be lower (supposedly by 1 inch of mercury for each. a vacuum gauge measures the vacuum pressure in an engine, helping identify performance issues such as poor. if the vacuum reading is pretty steady but cranking speed is not, you're probably looking at a damaged flywheel ring gear or starter. At idle, an engine should show a steady vacuum reading between 17″ and 21″. Intake manifold vacuum is a key indicator of engine. a vacuum gauge can help determine engine state or problems, including the following: Quick guide to vacuum gauge readings. how to use a vacuum gauge on a carbureted engine to diagnose problems.
