Why Does the 10th Generation Civic Shake When Starting?

[LeJune]

The reasons for the shaking when starting the 10th generation Civic are: 1. Severe engine carbon deposits, where the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture and making starting difficult; 2. Ignition system issues, such as poor performance of the ignition system or spark plugs; 3. Unstable oil pressure, abnormal fuel pump supply pressure, or incorrect readings and poor performance of the intake pressure sensor; 4. Aging engine components, where the engine mounts can no longer absorb the minor vibrations during operation. The 10th generation Civic is a compact 4-door, 5-seater sedan under Honda. Taking the 2021 Civic as an example, its body dimensions are: length 4517 mm, width 1799 mm, height 1434 mm, with a wheelbase of 2700 mm.
