I have a 2000 Gs300 I’ve had the issue for maybe three months today I finally scored a throttle body locally for a $100 it was off a 2004 Gs300 came home slapped it right on and started the car and it was worse than b4 the car would at least get me to work and back sometimes not do it at all but with this new throttle body its goes into limp mode immediately can I not use a 2004 or can it be my Computer?

TrueGS300

What are the codes in the computer?

You mentioned you've had this issue for 3 months. What exactly was the car doing before you replaced the throttle body?
