I still have not fixed mine. Still having the same issue. Code thrown is camshaft circuit bank 2. I have replaced a fuel injector I thought I might have damaged, I have replaced the plugs, moved coil packs around. It could be the "cheap" eccentric shaft sensor I had to install because I broke the original. I am stuck, and as much as I understand how this engine works, I just cannot find a definite way to troubleshoot an exact cause without throwing money at it.. Sorry I cannot help. I wish I did know, because it's really p*ssing me off that I cannot get this completely fixed...
