What is the reason for the 8th generation Accord's RPM increasing but speed not increasing?

[McDaniella]

The reason for the 8th generation Accord's RPM increasing but speed not increasing is poor fuel pump performance during normal vehicle operation. Below are relevant details: 1. Insufficient fuel pressure: Poor fuel pump performance, clogged fuel filter or injectors, lack of power during acceleration, which indicates clutch component failure. The occurrence frequency increases with rising temperatures. Throttle body issues, sticking or stepper motor failure. Exhaust system or catalytic converter blockage. Electrical circuit open or short circuit, poor conduction. 2. Throttle: The throttle refers to the control device that regulates engine power (thrust). In piston aircraft engines, the throttle controls the carburetor's throttle valve opening to regulate cylinder filling, thereby determining the engine's output power.
