I followed your recommendations and check for vacuum leaks. I found the O rings leaking and replace them.
(By the way the bottom one is hard remove the housing ...Someone recommend cutting the old ring and try to replace the new with out remove the housing. Don't do it! It will brake! What can you do is.. Use a screwdriver when sensor almost out and gentle force up and it will come out)
Thanks again!!

The P0171 & P0174 codes are often related to a vacuum leak and this information should help http://jagrepair.com/images/AutoRepairPhotos/P0171.pdf now remember that I said most of the time. In my quest to find my leaks I used throttle body cleaner but I understand the soapy water is as good. This forum has a lot of information relating to vacuum leaks but you will need to do a search. I have other information on vacuum leaks on my page if you wish to view it.
