What Causes the Engine Shaking in Roewe 550?

[VonPenelope]

Roewe 550 engine shaking may be caused by: 1. Dirty throttle or excessive carbon buildup in the fuel injectors, which are common reasons for shaking during idle; 2. Malfunctions in the ignition system, such as poor performance or spark plug misfiring, can also lead to such issues; 3. Abnormal fuel pump pressure or a faulty intake pressure sensor often results in body shaking, requiring timely repair or replacement; 4. Aging engine mounts (also known as engine cushions) could be another cause. In terms of dimensions, the Roewe 550 measures 4648mm in length, 1827mm in width, 1483mm in height, with a wheelbase of 2705mm.

When driving my Roewe 550, I encountered engine shaking issues, which turned out to be due to aged spark plugs. Spark plugs are responsible for ignition; if they have excessive carbon buildup or are worn out, the cylinders will ignite unevenly, causing the entire engine to shake. This is especially noticeable when starting the vehicle, with unstable idling and vibrations in the steering wheel. A friend of mine suggested it could also be a fuel system issue, such as clogged injectors leading to uneven fuel injection, which can cause similar symptoms. Try cleaning the throttle body and fuel injectors. Additionally, if the ignition coil is leaking electricity or has poor contact, it can also cause the engine to shake. I recommend first checking the condition of the spark plugs yourself. If that doesn’t help, take it to a professional shop for inspection—don’t delay to avoid damaging the engine. Ignoring the shaking may accelerate wear, increase fuel consumption, and even affect driving safety, so timely action is the wisest choice.

Having driven for over 20 years, I can say that 80% of engine vibrations in the Roewe 550 stem from the ignition system or fuel supply. Spark plugs tend to accumulate carbon deposits and fail after prolonged use, while aging ignition coils are a common issue. Clogged fuel injectors or obstructed fuel lines can lead to uneven combustion. A dirty mass airflow sensor can cause insufficient air intake and unstable idling. I once experienced body resonance due to loose mounts—it felt like the engine was about to fall apart. Key points: Significant shaking during cold starts often points to spark plug issues, while vibrations during acceleration require checking the fuel pump or injectors. Regularly replace the air filter to maintain clean air intake and don’t skimp on maintenance. You can inspect the spark plugs yourself for burnt electrodes, but complex issues require an OBD scanner to read trouble codes. Don’t ignore it—prolonged neglect leads to worse engine performance and costlier repairs.

Engine shaking issues often stem from several key components: worn-out spark plugs that fail to ignite properly—try replacing them; faulty ignition coils that cause weak or interrupted sparks; clogged fuel injectors leading to poor fuel atomization and uneven combustion; throttle body carbon buildup affecting air intake; or deteriorated engine mounts reducing vibration damping and increasing cabin vibration. Roewe 550 owners should first inspect simple parts like the air filter for dirt and check spark plug condition. If idle shaking is severe, consider cylinder pressure imbalance or misfire. Diagnostic steps: listen for abnormal noises during startup and check the dashboard for warning lights. Address issues early to prevent cascading failures.
