Hello, good day, I wanted to comment on my problem if you can help me (in the video that I leave you can appreciate much better). The issue is that when I turn on my Ford Focus 2013, it happens to me that regulates badly and a rare noise from the engine is heard. I am not a specialist in the subject, but my mechanic saw it and still can no longer fix spark plugs, cables, butterfly and battery body, but the problem persists. Thank you!
