I haven't really noticed this problem until just in the past few months or so. It seems like that when my car is either idling or when I am at a stop light with my foot on the brakes, my car seems to have a slight rumbling. It used to be pretty smooth and there was no rumble or noise. I thought it would be fine after changing the oil and replacing the air filter, but still getting the little rumble every once in a while. Now it's more constant. Anyone know what's going on?

This is a 2006 civic LX automatic and with about 26000 miles on it.

is your idle fluctuating?? like it revs up then goes down to regular idle rpm then jump back up??
if so, its a vacuum line. im not too positive if the vacuum line diagram is under the hood cuz i never looked under mine

It's not fluctuating, when it idles the rpm stays the same.

my 06 ex does the same thing the deal has looked at it twice first changing the belt and tensioner then motor mounts and still there so if anyone knows i would also love to hear the fix.

haha wow weird guess I'm not the only one. Did the dealer charge you for it? I'm thinking about letting them know next time I go in for the oil change

I had less than 36k on the car and it was still under 3 years from original purchase date so they can't charge you unless it is considered abuse. which you said it only has 26k on it your fine. my car still has that problem but i am out of waranty and have to fight with honda care extended warranty. I have noticed it only at idle at a stop in gear mostly but even in neutral or park with the steering wheel turned or a/c on it can be re-created. feels and sounds like the car is loaded up, kinda like you are power braking the motor or a mount is rubbing the body who knows my dealer says they are stummped.

Oh, you got the extended warranty. I think my dealer will try to charge me as much as possible to even look at it. So I hope it's nothing major.
