It has to do with a the purge valve for emissions. I have no idea what your talking about with donations. I'm just taking time out of my day to help people. I don't know the people that run this site or the "2carprosMasterTechnicians." I know that people are on hard times and would rather try to fix their on car. That is what I am trying to help people with. I know that people ask questions on this site all the time. I have answered about 200 questions in the last 3 days to try and help people. I have nothing to do with this site and don't know what kind of experience the 2carprosMastertechs have. Just thought I would share.
