title pretty much says it all.

it sounds weird.

it may be related to my idle issues, i dont know. any thoughts? it appears to be coming from the engine bay.

my car has been acting odd lately... i think it may be time for a dealership visit.

But seriously, do you think it might be coming from the intake? where in the engine bay?

 

^^ Repost!

 

Does it sound like a wind noise? Like a low whistle?

That's the sound mine makes when it's cold out. It doesn't seem to matter whether I have it in gear or not, but it happens mostly when I'm coasting and goes away as soon as I apply the brakes.

 

^ yeah thats it. any clues as to what it is?

and lol MM & Tex.

 

cold tranny fluid? what fluid are you running?

I notice with my redline shockproof heavy that cold winter days cause it to whistle until the trans fluid gets up to temp.

 

Air pump for emissions?

 

Just let it warm up.

 

Just kind of a wwwwwwwwwwwwwiiiiiiiiiiiiiiiiirrrrrrrrrrrrrrrrrrrr rrrrrrr. Type sound? no frequency changes? Mine does this too I had deduced the secondary air pump may be getting some high resistance, but still seems to be working. So I haven't fixed it yet.

 

it maybe tranny fluid, its possible. im running redline mt90.

 

air pump.

 

Well, then, now's the time to ask: what's the car do with an air pump? Why would the noise stop when I apply the brakes?

 

I haven't heard Bubb Rubb in forever! That made my day!

 

air pump only pumps air into the exhaust, for emissions, note we dont have a pre cat like most cars. only does this when its cold and the car is just started.
