How your car feels when you start the engine and begin driving is important. This is the time when you are most likely to notice unusual sounds or vibrations. All car engines vibrate to some degree, but it should be smooth. If your car’s idle RPMs are erratic or the car shakes when you are driving it needs some attention. If you ignore unusual car vibrations, it can lead to worse problems down the line.
A car engine needs the right mixture of spark, fuel and compression to give you a smooth ride. Many systems work together to create this precise blend of elements. If one of these systems fails your car will vibrate or shake, so this is a good place to start troubleshooting.
