Doing a little maintenance on the Sable, and I'd like to clean the EGR tube. Getting an EGR code and I want to eliminate this before I spend money on anything else ($3 gasket if I'rm ight, $80+ parts if I'm wrong - the old Maximas had a similar design and had this problem). Having some trouble getting the tube out, thought I'd bounce it off you tech-minded guys. Pic's worth a thousand words: I can obviously get the top of the tube off, just by removing the EGR valve. I can't for the life of me think of how to get the bottom off. It threads into the rear exhaust manifold, nut is about 7/8" +/-. I can get a wrench on it, but can't really turn it. I was thinking of a tie-rod end type tool, but my biggest one is 17mm. Once it's out, I'll put some anti-seize on it and it will be much easier to get in, so I'm not concerned about that. Thoughts?
