[StMadeline]

Here are the reasons why the Envision displays reduced power: 1. Carbon buildup in the engine. 2. Fuel system malfunction. 3. Intake system malfunction. Here are the inspection methods for the Envision displaying reduced power: 1. Check whether the intake camshaft solenoid valve and the engine oil pressure solenoid valve are malfunctioning. 2. If a malfunction is found, it should be replaced promptly. Here are some extended tips for using a car engine: 1. Avoid driving in neutral. The engine itself has a fuel-cut function during deceleration, and driving in neutral is not conducive to fuel economy. 2. Pay attention to observation when using the vehicle. If oil is found on the ground, determine whether there is an engine oil leak and communicate with the car 4S shop in time to eliminate potential safety hazards. 3. For vehicles equipped with a turbocharger, do not turn off the engine immediately after high-speed driving or climbing a slope. Let it idle for 10 minutes before turning it off. 4. When brake fluid is mixed with or absorbs water, or impurities or sediments are found in the brake fluid, it should be replaced or carefully filtered in time.
