Whistling noise at acceleration? Options

[HectortheRican]

the only thing else i could tell you is maybe you have a bad ground wire for sounds, cus that follows acceleration also. did you work on anything electrical?

If that's the reason, it must've jostled loose because I haven't done any significant electrical work that could cause something like that.

I use to hear it from a small crack in my rubber intake piping

My SRI has an aluminum pipe and all the holes are plugged.

I used to have a similar problem on my old 7A... though I think it was from this long crack along my exhaust manifold (at least that was the only thing I could contribute it to... could have been intake, never thought of that... its easy enough to check the exhaust manifold though.

Possibly... I have an eBay SS header, so it could be cracked. But if that was the case, wouldn't I be smelling more exhaust fumes? Because I haven't noticed anything like that.

It sounds like you have either a bad tire causing this problem or a wheel bearing that is failing.

I have the same problem but I didn't always have it. i believe its just the tb breathing but also think the iac port plays a bigger part.
never had the problem until i cleaned out my tb and iac, and i had the ****tiest intake hose that leaked like crazy but it didn't whistle before. sometimes i run without the hose on tb and u couldn't convince me its anything else.i think it has to do with like the air splitting between the butterfly and iac port.
im not positive but i stand by the theory still. maybe this helps in some sort of way
