Hello,

Does your vehicle have service engine light on?
Please refer to this link that shows how to diagnose a hesitation:

Please refer to this video of how to diagnose a misfire:

Typically a misfire can happen when the spark plugs gets old/dirty, sometimes it can happen if the spark plug wires becomes deflective.

Please let me know if you have any questions.

Thank you.
