What Causes Heavy Throttle with Resistance When Driving?

[RicardoFitz]

The reasons for a heavy vehicle throttle are: 1. Power assist component: Damage to the power assist component; 2. Transmission part: Obstruction or increased friction in the transmission part; 3. Throttle: A dirty throttle causing insufficient air intake. The methods to address a heavy vehicle throttle are: 1. Cleaning: Clean the throttle, wash the fuel injectors, and lubricate the throttle cable; 2. Installation: Install an electronic throttle accelerator. Precautions for pressing the throttle are: 1. Gentle operation: Press and release the throttle pedal gently and smoothly; 2. Swift action: Coordinate the release of the clutch with pressing the throttle swiftly; 3. Appropriate gear selection: Choose the right gear to keep the engine running at medium speed and larger throttle most of the time to save fuel; 4. Throttle operation: Before driving or turning off the engine, release the throttle pedal first and avoid revving the engine abruptly.
