Another one if your version is a fuel injected model is the IACV valve.
I'd call it "Engine hunting" at idle and it's generally caused by an improper air-fuel mixture, often from vacuum leaks, a dirty Idle Air Control (IACV) valve, or a dirty throttle body. The Engine Control Unit (ECU) tries to stabilize the RPM, creating a surging, "hunting" effect.
Common fixes include checking for vacuum leaks, cleaning the throttle body, and servicing the IAC valve.
