What Causes Body Vibration When a New Car is in P Gear?

[RichardMarie]

The reasons for body vibration when a new car is in P gear are as follows: Increased Engine Load and Reduced Power: For automatic transmission models, slight vibration when shifting gears is a normal phenomenon, which is caused by increased engine load and reduced power. Abnormal Engine Idle Operation: If the vibration is more noticeable, it indicates abnormal engine idle operation. It is necessary to inspect the aspects that may cause abnormal engine idling. If the fault light is on, locate the faulty part according to the fault code. If the fault light is normal, check whether the air filter is excessively clogged with dust, then check for any cylinder misfires, and further inspect whether the high-voltage ignition system and fuel injection system of the misfiring cylinder are functioning abnormally.
