Lately I've been hearing a fluttering noise while I'm accelerating from a stop, it's very noticeable. I did some searching around and I came up with the conclusion that it might be an exhaust manifold leak. I have a 2005 DCSB, I read there was a TSB for the exhaust manifold leak, am I too late for the TSB? Is it an easy fix if I do it myself? Or could it be a different problem?
Any input would be greatly appreciated.
Thanks in advance.
