Default Noise at start up.

When I turn the ignition and the car starts to turn over I hear a
sound that is like some one saying "shhh" loudly. I sounds like a
slip of some kind. The car just started doing this in the last few weeks.
It does it every time I start the car now. Could it be the starter going out?
The car idles fine and the belt does not squeak while running, so I think
we can rule out bad belt and ignition. What do you think guys? I usually
only hear it once per startup in between the firing of the pistons. It sounds like rr rr "shhh" rr rr vrum, and then the car starts.
Thanks.

I had somewhat of a "shh" sound after I changed plugs. I had a plug loose and you could hear it blowing through the threads. Thats the best advice I can give.

Was this only on start up, or could you hear it all the time while the car was running?
