C8 2.0 petrol throttle body tps calibration

[f1iceman]

Hi I am new so hello to everyone that reads my post.

I have recently bought a c4 sx 1.6 petrol and a c8 sx 2.0 petrol.

Now I have bad fuel economy and very sketchy vague car response to accelerator.

I was actually wondering if I have to do a full reset or a calibration of the throttle body after I take it off to clean it out properly.

Also is there an accelerator reset that can be done aswell.
Lewis say 4.7 to 73.8 for pedal range.

I have no issues with idle just crappy throttle response just don't feel in control 100% pulling off is unpredictable.

Thanks for any help.

Also I have no codes apart from a generic 0415 wheel speed sensor should be.
