What are the reasons for a CVT transmission not accelerating when the throttle is applied?

[VonKimberly]

CVT transmission not accelerating when the throttle is applied can be caused by carbon buildup issues or intake problems. Below are specific explanations for the reasons behind a CVT transmission not accelerating when the throttle is applied: Carbon Buildup Issues: Carbon buildup includes deposits in the cylinders, throttle body, spark plugs, and intake pipes. These areas are directly related to the engine's power output. When there is excessive carbon buildup inside the engine, the ignition energy decreases, and intake efficiency drops, ultimately leading to reduced engine power. This results in sluggish acceleration and a muffled sound. Cleaning the carbon buildup is necessary. Intake Problems: Air is one of the power sources for the engine. If the air filter is clogged due to prolonged use without timely cleaning, insufficient air supply will cause the air-fuel mixture to become too rich, reducing engine power. For vehicles equipped with a turbocharger, if the turbocharging system malfunctions, the engine will remain sluggish and fail to deliver power even when the throttle is applied. A detailed inspection at a 4S shop is required.
