Why does the Fit shake when starting?
2 Answers
Reasons for severe shaking when starting the Honda Fit: Poor contact of the clutch lining, surface hardening, or adhesion of sticky substances can easily cause clutch trembling; warping, tilting, and deformation of the driven disc, which leads to irregular contact of the clutch lining during engagement, preventing smooth pressure increase; loose or severely worn components, locked or loose clutch operating mechanism, severe wear of the clutch spline hub, or bending of the transmission's first shaft. Below are additional details: 1. Solutions: Reattach the clutch lining; adjust or replace the driven disc; replace the clutch disc or corresponding transmission parts. 2. Fit Performance: The third-generation Fit (FIT) is the first to feature Honda's new engine. The new 1.5L direct-injection DOHC i-VTEC engine delivers a maximum power of 96kW/6600rpm and a maximum torque of 155N·m/4600rpm, leading its class in power performance. Paired with the new CVT transmission, the third-generation Fit (FIT) achieves the lowest fuel consumption in its class at just 5.3L per 100km.
When I first drove the Fit, I also experienced shaking during startup. It felt like the car was rushing forward while the idle was unstable. This could be caused by aging spark plugs or faulty ignition coils. After several years of use, the ignition efficiency of spark plugs decreases, making the engine prone to shaking at low RPMs. Another possible issue is the clutch. In manual transmission cars, severe wear on the clutch plates can lead to uneven engagement. Additionally, excessive carbon buildup can affect the throttle opening, especially noticeable in stop-and-go city driving conditions. It's recommended to perform a self-check first—observe if there are any abnormal noises in the ignition system or if the exhaust color turns black. If a simple throttle cleaning doesn’t help, it’s best to visit a professional shop for a comprehensive inspection, as this directly relates to startup safety. Don’t overlook the condition of the transmission fluid or whether sensor data is normal.
