Have tried giving full service. Just bought the car, the car has been stood for 4 months. And when driving after service it drove fine for 15 minutes and then it was like it was missing.

It's misfiring after service of changing oil filter, air filter, oil and new spark plugs.

Hello,

An engine can misfire due to having faulty ignition coil(s).
Is your check engine light illuminated? Typically when the engine misfires the engine light gets triggered.
Check the codes and see what its indicating.

This can help you with the diagnostics of the issue.
Keep in mind you can have running/idling issue if the engine is not getting enough fuel.

Please let me know of any questions.
Thank you.
