100 years old Suzuki alto engine jitter reasons.

The reasons that may cause the 8-year-old Suzuki Alto 100 engines to shake are: 1. Spark plug problem: outdated or blocked spark plugs will affect the combustion of the engine and lead to jitter. 2. Fuel problem: If there are too many impurities in the fuel or the fuel pressure is insufficient, it will also lead to engine jitter. 3. Air filtration problem: Air flow will be reduced during air filtration or blockage, which will make the engine burn insufficiently, thus leading to jitter. 4. Maintenance problem: If a certain part of the engine (such as cable or connecting rod) is damaged, it will also lead to jitter. 5. gasoline pump problem: if the gasoline pump doesn't work or doesn't push enough gasoline, the engine will shake. The above are some reasons that may lead to engine jitter. It is recommended that the owner send the vehicle to a professional maintenance station for inspection and maintenance.
