Ahsan Allahu ilayk Ustadh I frequently experience some air bubbles passing through my middle to front passage when I lift my leg up for washing my feet during wudu or while going to ruku’/sujood. I’m 100% sure that something is going on like popping of air bubbles, does this count as breaking wind?

Ustadh AbdulAziz al-Haqqan
No, air bubbles do not nullify the wudu. Don't fall into waswas with these thoughts.
