2017 hyundai tucson 160000 miles automatic. 

Car sputtering while going up a hill along side high rpm around 400000 loss of power and squealing noise when pressing on gas pedal. Drives a little better when putting it in sport mode 
 I've changed sparkplugs, cleaned out throttle body (made sure to not touch with fingers and opened with pressing gas pedal) changed cabon filter, air filter and cleaned the map sensor. There's not many videos on this car with theses issues please help thank you

How old is your fuel filter? Have you checked fuel pressure? Performed a diagnostic scan?

high rpm around 400000

that is very high. I'm surprised the engine isn't orbiting the Eath 😆
