I recently rebuilt the turbo on my 06 F-250 6.0 due to excessive lag, no power and blowing smoke. Did not fix problem so I pulled the EBP sensor that I have also recently replaced. The last time I replaced it, I bumped the engine over for a second and watched the exhaust blow out of the line with the sensor removed. I just removed the new ebp sensor and did the same thing and no exhaust would come out. I pulled the tube and it's clean. Ran a pipe cleaner a good six inches down inside the fitting on the manifold and nothing is clogged yet no exhaust will come out? Any ideas?
