I've had several threads over one ECMlink for a couple weeks asking about what could cause my issue but no one ever responds, if they do its something completely unrelated to my question or problem.
Like the title says I have an issue with my engine it started to become obvious about 2 weeks ago, barely stays running on a cold start if I try to give it gas it coughs out and dies. It can be seen in my logs as the wideband goes from full rich to full lean then dies. It just seems like an issue I've had before with a carburated engine that had a blown power valve that was leaking vacuum. Except according to my boost gauge at cold idle I'm seeing almost 25inhg vacuum. So I'm at a loss. I've done several boost leak tests and cant find a single leak so what would cause these symptoms and if its a vacuum leak as I thought, what would cause a vacuum leak that wouldn't cause a boost leak?
