What are the reasons for reduced engine power in a car?

[LeEvangeline]

There are several reasons for reduced engine power in a car: 1. Excessive carbon buildup on valves and intake pipes, which is a common cause of power loss. The solution is to have professional auto technicians clean the carbon deposits and check if spark plugs need replacement; 2. Inspect the fuel supply system for any blockages or vapor lock in fuel lines, check if the fuel pump is functioning properly, verify if the carburetor float chamber fuel level meets specifications, examine if the air filter is clogged, and check for any exhaust system blockages; 3. Improper tire pressure, especially when tires are underinflated while carrying multiple passengers, can significantly affect performance. Therefore, ensure proper tire inflation according to the recommended pressure indicated on the vehicle's tire pressure chart.
