I want to replace my troublesome pipe with the updated version (less work than the cleanout you suggest) but it looks like a huge job to get at the intake manifold side. I wish someone would do this in the DIY section and post pics or perhaps I'll hafta take my next vacation to Gainesville and let a pro do it
Ronald - a gentle tap tap with a metallic hammer may relieve the bind your valve has probably been twisted into, do not put too much ass into it (in light of Steve B's advice)!!
Don't forget you haven't even confirmed this is a blockage yet! Just tighten it back up and go to AutoZone and get them to read the friggin codes!! Youre makin' me nervous
