Engine Vacuum Gauge Bouncing At Idle. A quick opening and closing of the throttle should cause the vacuum to drop below 5″ then rebound to 21″, or more. A vacuum gauge needle that vibrates rapidly at idle and then seems to smooth out with rpm can indicate bad valve guides or a bad cam lobe. When your engine vacuum gauge fluctuates at idle, you may have a worn valve guide or uneven compression caused by broken. With the engine idling, continued fluctuation of 1 to 2 inches may indicate an ignition problem. You can get a quick basic appraisal of engine condition by connecting a vacuum gauge to the manifold and a tachometer to the ignition to check vacuum and rpm at cranking speed. If the idle goes over 800 adjust curb idle screw until back at 800 rpm, recheck idle mixture screws again. Warm up the engine first, then shut it down and General ignition issues or sticky valves. At idle, an engine should show a steady vacuum reading between 17″ and 21″.
