Hello I have a 2015 dodge dart. I received a code for my purge valve and purchased one off Amazon and put it on my self. Before that I had a small leak which has worsened a bit but I thought it was coming from the purge valve. I recently found out it is coming from the the upper and lower radiator hose. When I crank my car it has a rattle and shake coming from behind where the purge valve sits and sometimes my car acts like it doesn’t want to start it shuts off or I have to give it a rile to stay crunk. Is the purge valve malfunctioned? Or is the leak in the radiator hoses causing the purge valve to malfunction?
