Thanks Feddy, to pull this manifold off looks like a major job. I cleaned out as much carbon out as I could where the tb bolts up to the manifold there looks like there is some type of swirl chamber that the egr must follow in and it was completely blocked so I cleaned the best I could{ bloke wants ...
