Hello good night, if someone has any ideas that may have happened.(I attach videos)
I got that noise after about 50 km of having changed a spark plug, all that noise to disappear after 150 km(1.5 hours) of travel. It's very strange because it's gone, there's no more noise.
When the engine was noisy, it issued the fault codes on several cylinders (3-4-6)
I deleted codes and they have not returned. There are no strange noises either.-
