Play a passage on just the open strings to check that you know what your right arm is doing.
Try writing out the open-string version so that you know which open strings to play. Or, draw a bracket over groups of notes in your score and label each bracket with the string name.
This excerpt is from the Allegro of "Praeludium and Allegro" by Kreisler.
