Everytime I press my APP hold switch while ready to land on the right runway ATC advised me to, my plane starts to turn left or right. My autopilot is on and all. Why is that???
have you selected nav instead of gps?
You don't land on autopilot. You can approach the runway with the auto pilot set to intercept and track the correct course of the instrument approach to that runway. You have to set your Nav radios correctly so that the AP will follow them. For a visual approach in good weather using the GPS, see my previous post.
