What Causes Idle Vibration After an Oil Change?
1 Answers
The reasons for idle vibration after an oil change are as follows: 1. If the viscosity of the new engine oil is unsuitable for the vehicle, the fuel injectors may become clogged, leading to inconsistent fuel injection amounts from each injector. This results in uneven cylinder operation and causes engine vibration. The solution is to remove and clean them. 2. If the engine oil is not genuine or contains excessive impurities, it can lead to excessive carbon buildup. Over time, carbon deposits and oil sludge can clog the throttle body, idle valve, and intake ports, restricting airflow and affecting idle stability, causing vibration. These issues can be resolved by inspecting and cleaning the mentioned components with a cleaning agent without the need for removal.
