If you have “bucking” or “lack of power” hopefully this will provide a solution.I just wanted to state my appreciation for your efforts on this forum. My 2004 Murano has been running poorly for the last several weeks; primarily bucking (sometimes violently), and a severe lack of power. It was particularly bad when cold, but still quite bad even when warm. I had assumed it was some type of drivability issue (e.g a bad sensor) , although it did not trigger the Check Engine Light. I was prepared to take it to a dealer; when prompted by a friend I did a Google search for “murano bucking” and ended up reading this thread. The Bottom line is that based on a post on this thread I checked the intake hose for possible leaks… and mine was not only loose, it was partially disconnected. I slipped it back on and the problems was solved!! I am not suggesting that everyone on this thread has this issue, I suspect that there may indeed be other more serious issues… and you have my condolences. But, I just wanted to suggest that anyone with a “bucking” or “lack of power” issue at least check their intake connections before taking it in to the dealer. My thanks go out to those that took the time to post their comments about this issue.The intake connections are basically a source of air leakage between the Mass Air Flow sensor (attached to the air cleaner assembly), and the intake manifold. There are two rubber flex hoses that attach to a plastic housing using hose clamps, they appear to be the most likely areas for leakage; or in my case separation. But any air leak would have the same effect to some extent. Hope this helps some solve their problem.
