What Causes Engine Shaking When Starting a Car?
1 Answers
Engine shaking when starting a car is caused by aging or loosening of engine mounts: Engine mounts are rubber blocks placed between the engine and the frame, designed to reduce vibration and absorb shocks during engine operation, while also securing the engine in place. Once these mounts age or become loose, the engine's shaking becomes noticeably more pronounced. Another possible cause is engine misfire: Engine misfire refers to one or more cylinders not functioning properly, typically characterized by intermittent exhaust flow, severe shaking of the exhaust pipe, noticeable engine vibration, and sometimes accompanied by a sputtering sound. This is often related to faulty ignition coils.
