Not too likely.  I would suspect the Hall sender circuit or the ignition
controller inside the ECU (2.1l, right?)  You're getting extra ignition
pulses, either the driver is going nuts or the distributor is telling
lies.  I suppose it's conceivable that it's the coil, but I'm having
trouble conceiving it. <g>

Yeah, the false ignition pulses are telling everybody that the engine is
running faster than it is -- including the buzzer circuit.
