When driving a manual transmission car, if you hear a rubbing noise from the engine slightly above 2000 RPM, but it disappears above 2300 RPM, what could be the reason?

When the RPM reaches 2800, there's a loud roaring noise, but after 3000 RPM it disappears. What's going on? [Cover face]

The 2017 Land Cruiser with an automatic transmission struggles to accelerate when flooring the gas pedal, with the RPM not going above 2300, causing slow acceleration. However, when using cruise control, the acceleration is faster, and the RPM can increase. What might be the reason for this?

Hello everyone, could someone help me with this issue? When in Park and idling, if I rev the engine above 1600 RPM and then release the throttle, the RPM stays around 1600 for about ten seconds before it drops. This doesn't happen if I don't exceed 1600 RPM. Between 1600 and 2000 RPM, there's a noticeable jolt. Additionally, when shifting gears and slowly accelerating, there's a rattling noise between 1600 and 2000 RPM, but it disappears after 2000 RPM. Does anyone have any insights on this? I would really appreciate it. The car model is a 2016 30T two-wheel drive. Thank you very much!
