Throttle Body Relearn:
After replacing the throttle body, it's crucial to perform a relearn procedure to ensure proper communication between the new components and the car's computer.
Here are some methods to reset the throttle position sensor (TPS):
OBD2 Scanner:
Use an OBD2 scanner compatible with your car model.
Look for the throttle sensor reset feature in the scanner.
Follow the scanner's instructions to reset and calibrate the TPS.
Accelerator Pedal Method:
Turn the ignition to the ON position (without starting the engine).
Push the accelerator pedal down fully for about 20 seconds.
Release the pedal slowly and turn off the car.
Start the engine normally and check if the situation improves.
Fuse Removal:
Locate the fuse box (details in the owner's manual).
Remove the fuse related to the throttle body (leave it out for about 10 minutes).
Reinsert the fuse.
The throttle body sensor should reset.
Driving the Vehicle:
Drive the car on the highway at speeds over 40 mph.
Accelerate and decelerate slightly.
Repeat this process to allow the sensor to reset.
Additionally, there's a helpful YouTube video that specifically describes the relearn procedures after replacing the throttle body and the throttle position sensor (TPS) .
Check for Other Issues:
Ensure that the ignition coils, spark plugs, and front oxygen sensors are in good condition.

On a 2003 it is likely to be breaks or damage in the wiring harness that goes from the driver door into the door frame. All the wires from the driver door switch go though there. With constant opening and closing the wires can work harden, wires break, resistance increases and they burn out and short.
The wiring can be tested for shorts.
