idle noise
every minute or so, my engine, or something under the hood makes weird vacuum type noise that comes on for 3 seconds or so... and then goes away, it sounds like the engine is revving slightly, is this normal or should i be freaking out?

im pretty sure it also happens while driving, can anyone explain to me what this is?

thanks

Re: idle noise
^ words. Park it and put your head under the hood.. make sure your inside air is off so you dont confused that fan kicking on for the sound. Report back.

Re: idle noise
ok so there are 2 rad fans, one of them is going constantly, the other one keeps going on and off, and is pretty annoying sounding

is it supposed to be going on and off or is it supposed to be going constant?

Re: idle noise
although i really appreciate your opinion, i would prefer to hear something along these lines..

"hey man, i just got an 08 civic too and mine sounds exactly the same, so unless both our cars are ****ed, everything is good. "
