What Causes Heavy Throttle and Slow Acceleration?

[JesseFitz]

Heavy throttle and slow acceleration are primarily caused by excessive carbon buildup in the engine. The solutions are as follows: 1. Throttle body cleaning is required. Check for carbon deposits on the fuel injectors. Neglecting detailed maintenance during car servicing, especially for vehicles used over an extended period, can lead to excessive carbon buildup on the fuel injectors, resulting in poor acceleration. The engine, throttle body, and combustion chamber are most prone to carbon deposits, necessitating timely vehicle maintenance and regular cleaning. 2. Inspect the spark plugs for proper functioning; replace them if they are worn out. 3. Frequent start-stop driving in urban areas can also cause poor acceleration. 4. Using low-quality gasoline may lead to sluggish acceleration. Poor-quality gasoline contains impurities that prevent complete combustion in the engine, affecting acceleration and the filtration by the fuel filter. It is advisable to choose reputable gas stations when refueling.
