Maintenance/Repairs

I have a 2008 pontiac G6 2.4 with roughly 155k miles on it, i noticed 2 things i have to release gas pedal for car to shift gears, i also noticed about a week ago that the acceleration is slowing down it doesnt accelerate like it used to, now when i drive it struggles to go uphill ill be getting high rpm but not gaining any speed or very little speed. 2 days ago while i was on the highway the car slowed down significantly and i received “engine power reduced” and “service traction” notification. i parked aside for a few minutes and it started up normal and drove again. it seems to drive fine at lower speeds. i purchased it used with 60k miles about 7/8 years ago. I took it to autozone and a mechanic shop they checked it and provided me with codes not sure if it helps. codes are P0010, P0013, P0014, P0420. I replaced O2 sensor bank one no resolution though.
