I was out driving yesterday, and I suddenly heard a new noise from the engine.
When I apply pressure on the throttle, and the engine revs up it sounds good. As soon as the acquired speed is reached, and the rpm is stable at lets say 1000-1500rpm the sound/noise appears. The check engine light allso lit up.

If you check the video I attached, at 21sec the noise appears.

Do any of you pros know what might be wrong?

(I have checked the Oil, not much of a mechanic. hehe)
