A little of both...
The oil pressure sender died... Car read that it had zero oil pressue. Pretty scary - some of these engines have issues with failing oil pumps.
Turned out to be a flakey sending unit. Tested with a mechanical gauge, and pressure was right on spec.
Maserati FSM calls to remove the intake manifold to replace the sender. Replaces some hose clamps and vacuum lines that looked a little on the worn side while it was all apart.
