Ok so after the throttle body was installed the mechanic said that he was able to stabilize the car. Before you had to step on the gas for the car to stop making noises and it seemed like it was gonna shut off; so he took care of that.
But now he says that when the car is put on gear it shuts off. The thing just dies and that he will continue to dig in to see what’s going on.
He also stated that the people who did the head job did a tremendous job and that everything was put back in place perfectly.
Any ideas as to what could be wrong now?

Make sure the TPS is set to .65 ohm and the idle holes are clean on the throttle body.
Yes thank you for your response. I talked to the mechanic who said was on vacation, and he said that the TPS was perfect as it came in the part and he didn't move anything. He also said that somebody who works at Toyota is gonna bring some of the computer readers next week see if they can tackle the problem.

Cheers and happy new year to all

Ok the mechanic said the throttle body was faulty and that I needed to get either a rebuilt one from across the pond or a toyota one new from Arizona, and that the codes on cylinders 1 & 6 have moved to 2 & 5. He stybilized the shakiness but the car still shuts down as soon as he switches gears. What do u guys think?

Ohm the APP and TPS. If in spec, BS on the throttle body. Could be the stepper motor. But that can also be tested.

The throttle body was already swapped and a used one was put in and the scanner kept on saying the throttle body was bad. So, since the throttle body was used we thought of buying either a Chinese refurbished one for $450 or one from a Lexus dealer for $1100
But Idk if I should spend that kind of money on the car at this point, kinda exhausted of dealing with mechanics and buying parts that they thought were the problem and it turned out that they were wrong, etc.
sorry for ranting

It is not the throttle body if two did the exact same thing. Even if it is used. You need to find a different shop.

As soon as you put it into gear the car loses cylinders 1-6 and the fuel injectors for 2 and 5 go bad, the car begins to stutter. The computer is good
The scanner sometimes points to the throttle body but then it deletes the code, then on a different day it would point to the throttle body again.
