🔴 Yes — this is a common issue in both urban and high-load scenarios.

Possible causes:

Weak fuel pressure

Throttle lag

Ignition misfire or

Improper air-fuel ratio

Sputtering is more noticeable during rapid throttle demand like overtaking o r climbing inclines.

🛠️ Conclusion: Likely caused by a combination of weak fuel delivery and ignition delay, often worsened by dusty, hot conditions and poor fuel.
