My 2004 accord 4 cylinder accord idles around 600rpm. Every so often i can feel vibrations (although small) through the seat. I was wondering if this rumbling is caused by a low idle or if 600rpm is the correct idle setting for my car? Thanks!

 

should be 750-800-850 anything in that range.. 600 is a tidbit low i understand the vibrations ur feeling.. its almost like the car is just BARELY staying alive.. almost like its choking.. just turn up the idle a bit and it should be fine

 

Isn't it under warranty?? Let the dealer do it. Then they can also measure idle rpm with something more accurate than the dashboard tach.
