Introduction to the reasons why the Elysion does not accelerate when the air conditioner is on: 1. Incorrect valve timing, such as poor sealing of intake and exhaust valves. 2. The fuel pump malfunctions due to internal or circuit issues, causing overheating, poor operation, short circuits, or burnout, leading to insufficient or stopped fuel supply. 3. Blockage in the intake system, such as the air filter or air flow meter, preventing proper combustion with fuel. 4. Internal engine faults, improper maintenance, premature or abnormal wear, cylinder pressure issues, or other potential problems. Below is an introduction to air conditioner maintenance: 1. Comprehensive air conditioner inspection: When using the air conditioner for the first time in summer, inspect the air conditioning system, such as checking the refrigerant through the reservoir, whether the air filter is too dirty, and if there are any foreign objects in the radiator. 2. Pay attention to air conditioner cleaning: The air filter should be replaced regularly to prevent moldy odors. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning.

Last time I drove my Honda Elysion, I felt a lack of power when stepping on the accelerator after turning on the air conditioning, and it couldn't accelerate properly, which was really annoying. I think this is mostly because when the air conditioning compressor starts, the engine has to share some of its power with it, leading to insufficient output. This is more noticeable in smaller engines, and for a heavy MPV like the Elysion, it's even more likely to drag performance down. It could also be a fuel system issue, such as an aging fuel pump or a clogged fuel filter, where the higher demand when the air conditioning is on can't be met. Additionally, check the feedback from sensors—faulty throttle position sensors or oxygen sensors can cause the computer to automatically limit speed for protection. I recommend taking it to a repair shop to read the fault codes and also test the air conditioning load. If the compressor is consuming too much energy, it might need repair or replacement. Regular maintenance of the fuel system and coolant can help reduce such issues.

As a frequent driver of the Elysion, I've also experienced sluggish throttle response when the AC is turned on. The reason may be uneven power distribution, as the engine bears additional load when the AC is running, leading to slower throttle response. On the electronic side, the engine control unit might adjust fuel injection for energy savings, especially in high temperatures where engine overheating can trigger limitations. If oil pressure is unstable or there's an intake pipe leak, turning on the AC can more easily cause vapor lock. I always check first if the wiring from the throttle pedal to the control module is loose, as older cars often suffer from signal loss due to corroded wiring. Additionally, check if the alternator voltage is stable—if it's too low, the AC will draw more power. A simple approach is to start with basic fixes, like cleaning the air filter or replacing spark plugs, before moving on to professional diagnostics if needed.

When driving the Elysion, turning on the air conditioning causes the throttle to lag, and acceleration becomes sluggish. I suspect the engine is in a power-saving mode. Once the AC is activated, the compressor consumes engine power, making the vehicle perceive a high load and automatically reducing speed to prevent overheating. Possible causes include insufficient battery charge or worn spark plugs, leading to inadequate ignition energy when the AC is on. High oil temperature increases viscosity, potentially causing poor oil circulation. Check if the air conditioning system is functioning properly; if the compressor is old and overloaded, it may need replacement. I make sure to regularly change the engine oil and coolant to prevent recurring issues. If all else fails, try restarting the engine—resetting the computer might help.
