THROTTLE BODY THROTTLE POSITION SENSOR LOCATION

I Was Wondering Where The Tp Sensor Is Located On The Throttle Body, And If Any Tools Are Required To Mount It Properly.

It Randomly Jerks Between 50 To 60 Mph, And It Stalls Randomly Sometimes. I Believe It’s A Throttle Position Sensor, But I Don’t Know...

How Do I Replace It, And Do I Need To Program It?
