code p2119 & p2176 "engine power reduced" on screen & tcm light on dash.
replaced the crank sensor months ago due to car not starting, car worked amazing after. ever since the beginning of this month the car would turn off while driving. replaced the cam sensor yesterday car ran perfect. today all of this happened now... what would it be now? i called the dealership and they could care less of giving advice and just suggest having them look at it for 125 dollars. i understand these codes are either the throttle or the wiring or ecm. please help this car has a serious case of being a lemon lol
where do i start to check the problems?
i am very overwhelmed with this car and i searched it on here already and nothing clicked. any helpful links would be appreciated too

Looking at the Helm manual... it appears those codes are both related to the throttle blades not closing all the way, or the ECM not being able to detect the throttle blades being closed. A couple of options worth exploring - one would be the throttle relearn procedure (search here), the other would be pulling your intake ductwork and looking at the throttle body closely to make sure there are no obstructions or oddities about it. How's the car idling when parked and warmed up?
