Why does the Mazda6 have heavy throttle and lack power when accelerating?

Mazda6's heavy throttle and lack of power during acceleration may be related to fuel quality or a clogged fuel filter. Check if the spark plugs are faulty. Additional notes: 1. For new drivers, when acceleration is not needed, keep your foot on the brake pedal to avoid mistaking the accelerator for the brake in emergencies. 2. When accelerating, avoid flooring the throttle—doing so in an automatic transmission car may cause the transmission to downshift. 3. In lower gears, engine braking is significant, so avoid abrupt throttle movements to prevent jerking, which is uncomfortable and harmful to the vehicle. 4. For deceleration, release the throttle early and rely less on brakes; using throttle control is more fuel-efficient and comfortable.
I also experienced heavy throttle and sluggish acceleration when driving my Mazda6, which felt like a clogged intake system or excessive carbon buildup. If the throttle body is covered in oil residue, air can't get in, and the engine loses power. The fuel system should also be checked—for example, if the fuel injectors are clogged, gasoline can't spray properly, leading to slow acceleration. Additionally, if the spark plugs are worn out, the ignition efficiency drops, making acceleration feel weak. Don’t overlook tire pressure either; low pressure can drag the whole car down. I recommend first replacing the air filter or cleaning the throttle body. If that doesn’t help, take it to a repair shop for a thorough inspection. Safe driving is no joke.
