Thank you very much for that info and for the pic ! Yes they sealed that part , because the mechanic said he didn't wanted to change that sensor and that he could fix it ! But I guess still licking air '. Do u know if that same part is the vacuum system something ! Because when I put the computer on my car to clear the codes it says p0175 and p0172 and I looked them up and it says something about the vacuum system passing too much air !
