ka loses power after its warmed up HELP

[ddf2006]

(ka24de) ok so heres what happines, on cold starts she drives like a champ and pulls great! But once its warmed up and i turn it off and back on, it feels like i have 90 hp. :/ like when im driving normal its ok i guess but the minute i give more then 30% throttle it just gets loud and not go anywhere, like it wants to go but had and anchor on its bumper. I do have a check engine light for codes 32, 33, 34. i changed the knock sensor but im still getting codes for it. any help will be gladly appretiated. (excuse my writing errors, writing this will half sleep)
