Clearing check engine light

[Erika Silva]

Hi. My 2019 Ranger was idling rough in the mornings. It’s at 60k miles so I changed the spark plugs. I did not have a check engine light prior to changing the spark plugs, but now I do. Says misfiring on #4. I want to clear the check engine light but not sure how to do so. Truck is not misfiring or idling rough anymore.

Doesn’t it go off after driving a while?

If you had a code reader you could clear it. Maybe an auto parts store would lend you one.

Will try. Thanks

If the problem is really gone it will clear after enough driving cycles. If not, need a code reader. Some codes sort of stick. I had a crank relearn CEL that didn't go away until I did said relearn that was thankfully on my tuner box. Even when it was running without any apparent issues.
