My r3 ar move up from itself when I play ps4

Do you mean that your right control stick moves by itself? If so, you might be experiencing stick drift. For the case of non-wear based stick drift, this may be caused by contamination of dust and other debris over time in the potentiometers. This guide shows a method to clean the relevant components that may help for this scenario.

Alternatively, if a solution like cleaning out debris does not work, the issue may be wear-based stick drift, in which case a replacement of the control stick module or the potentiometers may be appropriate. This is a process that requires desoldering the relevant components and installing new ones. Tutorials for this process can be found on Youtube.
