What does engine power loss mean?
3 Answers
Reasons for engine power loss: 1. Excessive carbon deposits on valves and intake pipes. The solution is to have professional auto repair personnel clean the carbon deposits and check if the spark plugs need replacement; 2. Check the fuel supply system for any blockages or vapor lock in the fuel lines, whether the fuel pump is working properly, if the fuel level in the carburetor float chamber meets the specified requirements, if the air filter is clogged, and if the exhaust system is obstructed; 3. Poor tire pressure is also one of the reasons affecting car power loss, especially when the tire pressure is insufficient and the car is carrying more passengers. Therefore, tires must be properly inflated according to the tire pressure table indicated on the vehicle body.
Engine power loss simply means the car accelerates slowly, struggles to climb hills, and feels unresponsive when you press the accelerator. This could be a fuel system issue, such as insufficient fuel supply from the fuel pump or a clogged fuel filter, preventing the engine from getting enough fuel—like a person running on an empty stomach. It could also be an electrical system fault, like worn-out spark plugs failing to ignite properly or a faulty ignition coil, making it impossible to properly ignite the air-fuel mixture. Additionally, poor airflow can affect performance; a dirty air filter restricts intake, like a person running with a mask on and struggling to breathe. I’ve also encountered cases where a clogged catalytic converter caused poor exhaust flow, making the engine feel stifled and naturally losing power. These issues need timely diagnosis, or minor problems can escalate into major failures, leading to higher repair costs.
I hate it when my car loses power while driving. Even when I press the accelerator, I can't feel the push-back sensation, which makes overtaking particularly dangerous. Common causes for this issue include excessive carbon deposits, dirty throttle bodies and fuel injectors affecting combustion efficiency of the air-fuel mixture. It could also be due to sensor failures, such as incorrect signals from the oxygen sensor leading to an imbalanced air-fuel ratio, or leaks in the turbocharger's pressure relief system. Last time my car had power loss, it turned out to be a cracked ignition coil causing high-voltage electricity leakage and misfiring. Additionally, engine oil that hasn't been changed for too long can become viscous, increasing engine resistance and reducing power. If you experience these symptoms, it's advisable to first check for trouble codes, inspect the spark plugs and air filter yourself. If the issue persists, take it to a professional shop to test critical parameters like valve clearance and cylinder compression.
