What causes unstable idling and gasping during cold starts in Jetta cars?
1 Answers
Reasons for unstable idling and gasping during cold starts in Jetta cars: 1. Issues with the fuel supply system: Unstable oil pressure can lead to unstable air-fuel mixture in the engine, resulting in car shaking and unstable idling. Consider replacing the car's fuel filter, as prolonged use can cause filter clogging. 2. Aging engine mounts: If the car shakes increasingly during use but the power remains normal, it may indicate a problem with the engine mounts. 3. Excessive carbon deposits in the engine: If power also deteriorates and shaking persists, cleaning the engine cylinders can resolve the issue.
