2019 Tacoma Engine Knock

The tech at my dealer was telling me that they make a "knock" sound when they switch from port injection to direct injection.

 

Does this not sound like an engine knock? If not i will just let it be for now. I have 15K more miles to go before warranty runs out.

 

I think it's normal as well. I have a 2018 previously owned a 2005 as well I believe it is something to so with this new Atkinson motor never heard it in my old 4.0 motor

 

Run premium fuel, ethanol free see if that goes away.

 

Thanks! Will try Premium on it tomorrow. If i run premium will i have to keep using premium?

 

It sounds a lot worse than mine, but could be your camera.

 

My 2020 sr5 is much quieter than that, but then again only 7400 miles. So far its about the same when it was very new. Btw...you have a hell of a cracker jack dealer mechanic.
