... switch to a k&n drop in air filter, also clean/ spray out the throttle body air intake with some sensor safe spray & use a gas/ injector treatment like max 44, if yuh gas filter clogged might get some hesitation.

u sure the engine rattling or is it the transmission, changing with original toyota atf may not hurt ..
