Good morning,

The sensor is part of the throttle body and cannot be replaced without replacing the entire throttle body.

Why are you thinking you need the sensor? Is there a code?

No codes. Code reader want link. New fuel pump. Filter though exhaust was plugged; took apart still no change. Tune up, changed cam. Sometimes rev to 4 grand then no more. Butterfly open sometimes and surges for a second.

Okay, did you check the actual fuel pressure?

I would start there to be sure there is enough pressure for the fuel injectors.

No car idles perfect. Butterfly isn't opening when pedal is pushed.

Okay, how do you rev to 4 grand if the plate does not open?

If the throttle body is bad, it should code.

There is also a pedal sensor that controls throttle. I attached a picture of it.

You will need a real scan tool to monitor the voltages of the system to find the failure.
