What causes the idle shaking and jerking in the old Sagitar?
2 Answers
The reasons for the idle shaking and jerking in the old Sagitar are as follows: 1. Carbon deposits: Excessive carbon deposits in the car engine prevent the engine from running normally. Insufficient air-fuel mixture in the engine makes it difficult to start, and when the throttle is dirty or the fuel injectors are clogged with carbon deposits, it can cause jerking during idle. 2. Issues with the car's ignition system: Problems with components like spark plugs or ignition coils can lead to jerking during idle. 3. Problems with engine components: Aging engine mounts can also cause jerking. If the engine mounts are faulty, it will result in shaking and jerking of the vehicle.
As an owner of an older Sagitar, I understand the idle shaking and jerking issue you mentioned. This is likely caused by excessive carbon buildup in the engine, leading to uneven combustion that makes the engine jerk. The ignition system is another common culprit - aging spark plugs or faulty ignition coils causing unstable firing can result in shaking. The fuel system shouldn't be overlooked either; clogged fuel injectors causing insufficient fuel supply or a dirty throttle body restricting airflow can make the engine tremble at idle. Worn engine mounts also contribute by reducing vibration damping. I've found that regular throttle body and fuel injector cleaning helps alleviate this issue, and changing spark plugs is quite effective too. But it's best to have a professional shop run diagnostic tests to prevent the problem from worsening and affecting driving safety. With older cars, paying extra attention to maintenance is crucial.
