What are the most common causes of engine sputtering in a Honda City in Pakistan?

Engine sputtering can be a frustrating issue for Honda City owners, leading to poor acceleration and an uneven driving experience. What are the main reasons behind this problem, and does it affect both petrol and hybrid models equally? Could factors like bad fuel quality, clogged injectors, o r ignition coil failure be responsible?

Common Causes of Engine Sputtering:

Bad Fuel Quality: Poor-quality o r adulterated fuel, which is a common issue in Pakistan, can lead to incomplete combustion in the engine, causing sputtering and rough idling.
Clogged Fuel Injectors: Over time, dirt and carbon deposits can block the fuel injectors, causing an irregular fuel spray pattern and poor engine performance.
Faulty Ignition Coils: If the ignition coil is weak o r malfunctioning, it can lead to misfires o r hesitation during acceleration.
Worn Spark Plugs: Misfiring spark plugs can result in engine sputtering as the spark does not properly ignite the air-fuel mixture.
Air-Fuel Ratio Imbalance: If the air-fuel ratio is too lean o r too rich, it can cause poor engine performance, including sputtering during acceleration.
Throttle Body Issues: A malfunctioning throttle body can restrict the amount of air entering the engine, causing hesitation and sputtering.

Impact on Petrol vs Hybrid Models:

The petrol model is more prone to fuel and ignition-related issues, as these are typically the causes of sputtering in internal combustion engines.
Hybrid models might experience sputtering due to issues with the hybrid system, but it would usually present in different ways, such as hesitation during transition between electric and engine power.
