Check your TPS, it might be out of spec.

When was the last time you did a spark plug and plug wires change? Have you checked the gap on your spark plugs? Those would be my first two thoughts. After that maybe a fuel pump. That is if you have crossed off the electrical/ computer stuff. Or water in the fuel. THose are the mechanical systems that bounce RPMs.

Spark Plugs on a Rotary cannot be gapped. THey come from the manufacturer already pregapped.
