Yes, a dirty air filter can cause engine sputtering, particularly during idling o r at low speeds, by restricting the airflow into the engine.

How a Dirty Air Filter Causes Sputtering:

Reduced Airflow: A clogged o r dirty air filter can block the amount of air entering the engine, leading to an improper air-fuel mixture.
Poor Combustion: When the air-to-fuel ratio is off, the engine struggles to maintain smooth operation. This can cause sputtering, rough idling, o r hesitation during acceleration.
Decreased Engine Performance: Insufficient air supply can lead to poor engine performance, causing the engine to sputter and run unevenly.
How to Fix:

Replace the Air Filter: If the air filter is clogged o r dirty, replace it with a new one. A clean air filter allows proper airflow and helps the engine run smoothly.
Inspect the Intake System: While replacing the air filter, inspect the intake system for leaks o r damage, as this can also contribute to performance issues.
What to Do:
Check and replace the air filter if it is dirty o r clogged to ensure optimal engine performance.
