Momentary engine shaking upon startup is a normal phenomenon. If noticeable shaking persists inside the vehicle after engine ignition, it may indicate damaged engine mounts. Engine mounts are installed between the engine and chassis frame to absorb vibrations. Typically made of rubber, these components can harden and deteriorate with prolonged use. Other potential causes of startup shaking include severe engine carbon buildup, ignition system issues, unstable oil pressure, aging engine components, with common culprits being dirty throttle bodies or excessive fuel injector carbon deposits.

What Causes Shaking When Shifting Gears in an Automatic Transmission?

Automatic transmission shaking when shifting gears can be attributed to the following reasons: 1. The gearbox oil is too viscous and dense, causing the drivetrain to receive engine power more noticeably, resulting in a distinct vehicle shake. 2. It may be caused by a dirty throttle valve, excessive carbon buildup in the intake pipe leading to low idle speed, or misfiring in the ignition system (such as faulty spark plugs or ignition coils), as well as poor fuel quality. These issues are related to the engine's operating condition. Switching to N gear may improve the situation, but occasional engine shaking can still be felt. 3. It could be due to quickly shifting from D gear directly to P gear when parking and then turning off the engine. In this case, the transmission may not fully reset internally, causing shaking when shifting gears the next time the vehicle is started.

Should You Disconnect the Negative or Positive Terminal First When Removing a Car Battery?

Disconnect the negative terminal first, then the positive terminal. Here are some precautions to keep in mind when installing or removing a battery: 1. During installation, connect the positive terminal first, followed by the negative terminal. If you disconnect the positive terminal first, any contact between the battery and the metal parts of the car body will directly connect the positive and negative terminals, resulting in a short circuit. 2. When removing or installing the battery, always disconnect the negative terminal first and reconnect it last. If you disconnect the positive terminal first, any accidental contact between a metal wrench and the car body during the process can cause a short circuit. 3. Automotive electrical systems are characterized by low voltage, direct current, single-wire configuration, and negative grounding.

What Causes Engine Light On and Car Shaking?

Engine light on and car shaking are caused by vehicle malfunctions. The specific reasons are as follows: 1. Poor combustion of the air-fuel mixture in the engine. When the mixture in the cylinder is too rich, the vehicle may experience knocking and shaking. When the mixture is too lean, the vehicle may exhibit poor acceleration. 2. Apart from mixture issues, another factor is malfunctioning spark plugs, high-voltage wires, or ignition coils. Poor ignition system performance or weak spark plug firing can also trigger the engine warning light and cause shaking with insufficient power. 3. Abnormal fuel supply pressure and intake pressure sensor failures. Incorrect fuel pump pressure or faulty readings from the intake pressure sensor can lead to car shaking and power loss.

Why Can't a Manual Transmission Car Shift Gears?

Reasons why a manual transmission car cannot shift gears: 1. The positioning component of the gear lever's ball joint may have failed. 2. The gear lever can rotate freely around its own axis, making it impossible to accurately control the gear position. 3. The spherical working surface at the lower end of the gear lever may have worn out, preventing the gear lever from controlling the fork or the fork's groove, resulting in failure to engage or disengage gears. The former can usually be resolved through repair, while the latter requires replacing the gear lever. 4. The clutch may not be fully disengaging, even though the transmission's shifting mechanism is functioning normally. This can be resolved by adjusting the clutch or replacing clutch components. 5. The shift fork may be loose, severely bent, deformed, or worn. Although the gear lever moves into position, the shift fork does not move sufficiently, causing severe impact and failure to engage gears.
