Help Rattling noise from the engine compartment
I am new to the forum and I am trying to find some answers for my problem.
I recently bought 06 Nissan Murano SL with about 55000 miles.
The problem that i am having as i can see is the same as many other Murano owners.
Basically I am having a rattling noise coming from the engine area. It only happens when you accelerate and with in a range of 1200rpm to 2000rpm after that is gone.When in park or neutral you wont hear anything no noise at all. It only happens under engine load. When i start the vehicle in the morning the engine is a little bit loud and i would say acts lazy. And the rattling noise/sound like an old diesel engine shows up after few minutes of the engine running. I can hear the noise coming from the engine compartment, especially on the passenger side and is very annoying. So after driving for longer time maybe 30 minutes or more I can tell that the noise goes down maybe even goes completely away or its very small that i can't hear it . It could be still there but not like on the beginning.
I have been using high octane fuel and the oil has been changed so I think that's not the problem.
My opinion is probably the fuel damper because the rattle comes from that part of the engine.
Please help any leads what i should try.
