No power

[sketchkid]

So today I change the o2 sensors, note the past month I've change the fuel, fuel filter, spark wires and plugs, fuel pump relay, oil change. Today I got to drive it no dealing power after 2gear noticed I do have a vacumm leak but it has no power in when I get good in 2 gear videos below, could it be the clutch, or transmission fluid that needs to be change or what?

Fix the vacuum leak, check the intake bellows carefully (replace if its suspect), do a stomp test for codes.
