What causes the jerking sensation when starting a 2007 Honda Fit automatic transmission?
1 Answers
The main cause of the issue is the accumulation of carbon deposits in components such as the throttle body, intake manifold, and valves. When the engine is cold, these deposits absorb some gasoline, which then evaporates when the engine warms up. This leads to an overly rich air-fuel mixture during idle, causing the jerking sensation. Another possible reason could be minor engine oil burning. Here are some relevant details about the Honda Fit: 1. Introduction One: The Honda Fit is a compact car produced by Honda. It has a wheelbase of 2530 mm, with dimensions of 4109 mm in length, 1694 mm in width, and 1537 mm in height. The Fit is equipped with a 1.5-liter naturally aspirated engine, which is part of Honda's Earth Dreams series. 2. Introduction Two: The 1.5-liter naturally aspirated engine in the Fit has the model code L15BU. This engine delivers a maximum power of 96 kW and a maximum torque of 155 Nm. The engine reaches its peak power at 6600 rpm and its peak torque at 4600 rpm. It features direct fuel injection technology and uses an aluminum cylinder head and block, which helps reduce the engine's weight, improving both handling and fuel efficiency. The engine is paired with a CVT transmission. 3. Introduction Three: The CVT transmission enhances the car's shift smoothness and fuel economy. CVT transmissions are relatively simple in structure, consisting of only two pulleys and a steel belt. The steel belt can move along the pulleys, allowing the transmission to vary its gear ratios. Due to their simple design and fewer components, CVT transmissions are also more cost-effective to manufacture. 4. Introduction Four: The Fit uses a MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear. The torsion beam rear suspension helps maximize rear passenger space and trunk capacity.
