What causes shaking during rapid acceleration but not during gradual acceleration?
1 Answers
The reasons for shaking during rapid acceleration but not during gradual acceleration are: 1. Fuel system issues: Fuel line blockage causing poor fuel supply or fuel pump failure. To diagnose fuel pump problems, disconnect the fuel line and check the flow rate and volume of fuel; 2. Electrical issues: Check if the timing is accurate, inspect whether the spark plugs have aged, if the gaps are uniform, and if the gaps have changed; 3. Mechanical reasons: Check the engine's operating condition for any abnormal sounds, inspect the belt's working condition for looseness. A car engine consists of five major systems and two main mechanisms. The five systems are the fuel supply system, cooling system, lubrication system, ignition system, and starting system. The two mechanisms are the crankshaft and connecting rod mechanism and the valve train mechanism.
