does anyone know how to modify the air temperature sensors with resistors on a honda accord?

 

If you have a manual and the wiring diagram, you'll want to put the resistor in series with the sensor, preferrably between the sensor and the ecu input, not the source power or ground from the ecu to the sensor. I personally use a 5k ohm potentiometer to test for differences. It makes a difference on a turboed car, I didn't notice much on a NA GSR......
