Hello,
Typically an engine will misfire due to bad spark plugs.
When the spark plugs are bad, the engine will lose power it will idle rough and will hesitate on acceleration.
Now since they have been replaced, does the vehicle drive as it supposed to?
Any hesitation on acceleration or rough idle?
If those issues are fixed then the replacement of spark plug has fixed the issue.
