What are the symptoms of insufficient car power?

[Stacey]

The symptoms of insufficient car power are: 1. The car cannot accelerate even when the throttle is heavily pressed; 2. Power decreases, and the car body shakes; 3. Smoke comes out of the exhaust pipe. The reasons for insufficient car power are: 1. Dirty throttle body; 2. Poor quality gasoline; 3. Abnormal signals from the pressure sensor or throttle position sensor; 4. Low fuel pressure, clogged fuel injector or fuel filter; 5. Air leakage in the intake pipe leading to an overly lean air-fuel mixture. The solutions for insufficient car power are: 1. Clean carbon deposits from the cylinders, throttle body, spark plugs, intake system, and engine; 2. Replace with high-quality gasoline; 3. Clean the air filter; 4. Check the levels of engine oil and coolant.
