Odd problem with the IO-390 Thunderbolt in my RV-14A: whenever I pull the throttle completely back, the engine seems like it's idling around 650 RPM but the tach goes haywire, reading anywhere from 30 to 1250. Engine has even stalled on me twice when I completely closed the throttle during taxi back to hangar.
Engine runs fine otherwise. One Slick magneto and one Emag. Issue can be seen in this short video:

Any thoughts appreciated.
