Why is my Suzuki Cultus engine sputtering during acceleration?

Engine sputtering during acceleration can be caused by various issues within the fuel and ignition systems.

Common Causes of Engine Sputtering During Acceleration:

Fuel Delivery Issues: If the fuel injectors are clogged o r the fuel pump is failing, the engine may not receive the proper amount of fuel, causing sputtering.
Faulty Spark Plugs: Worn o r dirty spark plugs may fail to ignite the air-fuel mixture efficiently, leading to misfires and sputtering during acceleration.
Air Intake Problems: A dirty o r clogged air filter can restrict airflow into the engine, affecting combustion efficiency and causing sputtering.
Vacuum Leaks: Leaks in the vacuum system can disrupt the air-fuel mixture, leading to irregular combustion and sputtering.
Bad Fuel Quality: Low-quality o r contaminated fuel can cause the engine to sputter, especially under load when accelerating.
How to Fix:

Inspect Fuel System: Check the fuel injectors, fuel filter, and fuel pump for blockages o r faults. Clean o r replace them if necessary.
Replace Spark Plugs: If the spark plugs are old o r dirty, replace them with new ones to ensure proper ignition.
Replace Air Filter: If the air filter is clogged, replace it to improve airflow into the engine.
Check for Vacuum Leaks: Inspect vacuum hoses and seals for leaks. Replace any damaged components to restore proper airflow.
Use High-Quality Fuel: Ensure you are using clean, high-quality fuel from a reputable station.
What to Do:
Inspect and clean o r replace components like spark plugs, air filters, and fuel injectors. If the issue persists, have the vacuum system and fuel pump checked.
