Trouble code P0431. Warm Up Catalyst Efficiency Below Threshold Bank 2. When my suv accelerates I have a whistling sound. I have poor acceleration at 2,500 RPM.

If you hear a whisteling sound and have low power with that code, chances are the converter is plugged on that side. You need to have it checked for backpressure.

Let me know what you find.
