Engine light on and traction control light I change out the throttle body and still does it

Hello, the traction control warning will come on when there's a concern with the anti-lock braking and traction control systems, not so much a throttle body relationship there. I'd recommend having a diagnostic test of your anti-lock brake and traction control systems performed. This interfaces with "C" chassis modules, so a typical "code reader" may not work as those are made for "P" power train modules.
