i might go to toyota tomorrow and see if they can diagnose it with there computer iam not too sure on how to read the codes properly

You've read the codes fine. Code 43, no STA signal. Have you push started your car ever? This code can flag if you do. 52 is knock sensor and is far more serious, and is also probably the cause of your poor response. likely causes are faulty knock sensor and faulty ECU in that order. Is it a smallport or a ZE?

its a bigport gze afm motor and no i don't think i have ever push started it
