Car will run smoothly and randomly go on limp mode with CEL + VDC OFF + SLIP. If i turn off and on, it will go back to running fine. Or sometimes i have to do an idle relearn and then it will go back to being fine.

I initially thought it was a bad passenger throttle body so i swapped it out for a new one, issue still stays the same no matter what relearn i do.

Im pretty lost on what to do next, i’m starting to think it’s electrical and possibly my BCM is shot. Any help is appreciated.
