Could dirty fuel injectors be causing engine sputtering in my Suzuki Swift?

My Suzuki Swift has been sputtering when I accelerate, and I suspect the issue might be related to the fuel injectors. Could dirty o r clogged fuel injectors be causing this problem? How do I know if the injectors need cleaning o r replacement, and what steps should I take to address the issue?

Yes, dirty fuel injectors are a common cause of engine sputtering, especially during acceleration.

Signs of Dirty Injectors:

Rough idling o r misfires.

Sputtering o r hesitation under load.

Increased fuel consumption.

Poor throttle response.

Fixes:

Add a high-quality fuel injector cleaner to your fuel tank e.g., STP, Liqui Moly, etc..

If the problem persists, get the injectors professionally cleaned using ultrasonic cleaning.

In severe cases, replace faulty o r worn injectors to restore proper fuel delivery.
