What causes the idle shaking and jerking in the old Sagitar?

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.

I personally experienced the idle shaking issue with my old Sagitar, which felt like the car was twitching. Carbon buildup is a major problem; too much carbon in the combustion chamber disrupts smooth operation. Ignition issues like worn-out spark plugs or leaking high-voltage wires can cause severe engine jerking. Fuel-related problems, such as unstable fuel pump supply or a clogged air filter, also contribute. Additionally, aging suspension mounts reduce vibration absorption. Last time, I replaced the spark plugs and cleaned the throttle body myself, and the shaking significantly reduced. Such issues are easily overlooked but can damage the engine over time. It's advisable to address them promptly before they worsen. Maintenance is key—regularly checking filters and fuel lines can prevent problems. Safety first, drive with peace of mind.

From my experience, the idle shaking and jerking in older Sagitars is often caused by carbon buildup or worn ignition components. Aging spark plugs make ignition inconsistent, clogged fuel injectors cause intermittent fuel supply, and a dirty throttle body restricts air intake, making the engine jerk. Softened engine mounts also contribute, with failed damping making vibrations more noticeable. This affects driving comfort and can even accelerate wear. I've handled similar cases where inspecting and cleaning the throttle body or replacing ignition coils often solved the problem. Regular maintenance like carbon cleaning can prevent it. Don't ignore it; address it early to avoid costly repairs.
