2017 4runner trd pro bogging loss of power

Hello everyone! I have a 17 trd pro with 75k mi that has recently started experiencing some loss of power, hesitation issues. Basically when accelerating, it bogs like itís being flooded. No check engine light, no stored codes. Changed the spark plugs, air filter, cleaned maf, cleaned throttle body, no change. Anyone else experience this bizarre issue?!?

Clean fuel filter. If the filter gets dirty, the car won't get enough gas and will act like that.

Also, the fuel pump could be failing; not putting out enough pressure.

Agreed, check fuel pressure. Can a scan gauge do this? Also, clogged cat?

Wouldnít that cause a lean code?

OP did you ever sort this out. the only time I've encountered something similar is when a rodent had chewed multiple injector wires
