Poor acceleration

Changed plugs fuel filter and O2 sensor already.
Very poor acceleration and hesitation when engine warms up. Goes great cold. But slower than grandpa on a sunday drive once warm.
The fuel filter was exceptionally dirty and collapsed. But I think when it is cold if injector was blocked temperature would not matter. Same with low fuel pump voltage and vacuum. Maybe air sensor intake dirty. Only goes well if I super lightly accelerate as in, rest my shoe on it lightly. Need help my misses is on my tail to fix it.
