2007 lean bank 1, check gas cap, melting upper intake manifold
Recently purchased and was running fine until I lost power and gas mileage. After closer inspection egr
valve was melting upper intake manifold. Replaced egr
valve dpr sensor and egr
valve control module, and upper intake manifold. Still getting some extra vacume through the egr
control. I have been reading everywhere to try and figure out why only the bank one would be running lean with the lower gas mileage and rough low idle on start up. It idles fine after a few mins of running. I know terrible mess I'm about ready to wrap it around a tree and call it good haha. Any takers on what I should do next?
