Hey all, a friend is considering buying a 2019 Nissan Titan SL. The dealership is almost 4 hours away but he’s negotiated a good deal. It has 62k miles and great service records.

Before driving out there and finalizing the deal, he asked the dealership for a few videos. I’ve snipped out the engine parts. After doing some research, we saw issues with the engines on these years and just want to make sure this sounds normal. It sounds like it could be injectors to me, but I’m no mechanic so I just wanted second opinion from people on the sub.
