Signs of a bad air pump?
I have searched up to 7 pages of the forum and haven't found exact sympthoms of bad air pump. I know that it starts squeking when it's going bad, but what else.
The reason i'm asking this is, recently i installed torque brace and a heat shield for apexi intake. And somehow i get some kind of strange noise. It's mixed with mooing sound of that damn pipe. So I just want to know of any sings when the air pump is on it's way down.

At least the stories I've read, most people don't really notice any signs except for a bad idle (as the ECU is expecting the air pump to be functioning and it's not).
Most people just notice a bad idle and then see the air pump isn't working anymore.
BTW, I had a mooing sound. It was a worn out hose to the BOV.

My mooing sound comes from that pipe next to the air pump. It sound only at low rpm's below 3k.
I have normal idle, how do i check if the air pump works?
Disconnect that hose from her and see if it's sucking air?
Thanks

I started getting kind of a funny noise also when I installed my ETB. It sounds like a moo/rattling and it only happens when I rev it at relatively low RPMs say areound 1500-2500.

I have a short vid from my digital camera showing the pump at idle if that'll help, but I can't seem to get it hosted anywhere cause it's .MOV

You can also check to make sure air is blowing from the airpump by pulling the hose at idle.
If the airpump isn't working, first make sure the connection is good. Also make sure to check your AC fuse (as the airpump shares that fuse).
