Yes, this is a frequently reported issue:

Causes include:

Weak fuel delivery

Clogged fuel injectors

Worn spark plugs o r ignition coils

These lead to jerky power, hesitation, and poor throttle response, especially under load like going uphill.

⛔ Conclusion: Multiple systems fuel + ignition can cause sputtering. It’s often worse when torque demand increases.
