Help with location and replacement of fuel injectors

I’m new here. I have a 2002 prerunner with a 4 cylinder 2.7 engine. I’m getting a misfire in the number 4 cylinder. Changed out the coil pack and plugs. Next on the list is the fuel injectors. Where are they located and does anyone have any pics or video of how to replace them? Any info would be greatly appreciated. Thank you.

Theyre on a fuel rail off on the side of the engine. Should be able to remove the air tube above, one bolt in the front and one in the rear of the rail, and pull it off enough to wiggle out ur injectors. make sure to take engine oil and smear some on the orings before u replace them or the orings will shred and youll end up with a mess.
