Ok, if the noise is from under the hood I know it well. The intake manifold on the Honda 6 cylinder engine has a large internal volume. When the engine is idling the vacuum inside it is very strong because the throttle is closed. When you shut the engine off the vacuum bleeds off and make a very noticable sound.
Does this sound like the noise? Is this something new or has the car always done it?
i havent change the air filter my honda has 18,571 milies to it can you repeat again where is the noise coming from? thank you
If you have an automatic transmission its normal for it to shift differently when cold. There are a number of reasons , for emissions purposes why the car runs and shift differently . Most of it has to do with warming the catalytic convertors quickly......
If no one has done anything under the hood the filter is probably fine. Your next oil change, have a dealer check it and verify the cause of the noise also
ok i guess thats answer my questions do i still need to bring it to the dealer about the noise since youve mention its normal?
No, you don't. I would not make a special trip but if you go to the dealer for an oil change it cant hurt to ask about it , they should confirm what I have told you....
Have a good weekend.
