3rz-fe engine problems

[filo-lancer]

I have a 2004 hilux 2.7ltr 3rz-fe engine.....

in the last couple off weeks i've noticed my car is loosing power and when i put my foot down to take off the car is sluggish and eventually when it reaches about 40 - 60kmh in 2nd it kicks in and drive normal and then wen i change to 3rd and put my foot down after changing gear it does it again.......... pretty much in every gear is sluggish till it reaches a certain speed in every gear.....no engine light comes on.

when it idles and i rev it is still does it but not as bad as when im driving. idle speed is like normal i cant see hear or see any miss firing of the engine. idle is smooth.....

i recently changed the fuel filter, spark plugs, air filter, cleaned the air sensor, and tested my leads and they are fine....... pulled my fuel injectors out and cleaned them.... cleaned my throttle body, and changed my airfilter.......and the problem is still there...

anyone have any ideas of what it might be.....?
