What Causes Car Engine Shaking?
1 Answers
Car engine shaking can be caused by: 1. Dirty air filter: Delayed replacement of the air filter can lead to insufficient air intake, causing low idle speed and engine shaking; 2. Low spark plug efficiency: Affects ignition, which is a common issue. Replacing all spark plugs usually resolves the problem; 3. Abnormal water temperature: High engine temperature can cause early ignition timing, altered air-fuel mixture, thinning of engine oil viscosity, and reduced lubrication performance. Common causes include insufficient coolant, malfunctioning thermostat, non-functioning fan, or inaccurate temperature control switch. These issues should be addressed accordingly; 4. Clogged fuel injectors: Blocked injector nozzles can lead to uneven fuel distribution among cylinders, causing inconsistent engine operation and shaking. The solution is to remove and clean the injectors.
