Hey guys,

I have a problem lately in my car and I can't find what the hell is going on! When I step on the accelerator there is a freaking whirring noise and it freaks me out. If i move my foot off the accelerator it doesn't make that noise.

Anyone knows what could the problem be?

Information of my car:
*After Market Wheels: ASA AR9 Wheels F: 19x8.5 R: 19x9.5 (Weight of each wheels 27lbs)
*No tuning parts
*Car have been driven for 61,798mile (99,455km)
*It's a 2007 model IS300 2nd Generation Middle East Version
*usually drive at speed: 86mph~100mph (140kmph~160kmph) using tiptronic.

 

What's whirring?

 

Where is it coming from?? Engine? Tires? It could be even static from your speakers.. I forgot why the speakers do that when you hit the gas, one of my previous cars used to do this.

 

Could it be you shifting at the wrong gear on the tiptronic?

 

it's coming either from the wheels side or the engine side! I'm not really sure

I don't think I'm shifting at the wrong timing even when I put it on "D" Drive the sound is coming.

Usually I shift at 3.5 on the tacometer just like when you drive with the auto at an average speed it shifts when it reaches 3.5. I don't think it's wrong!

 

Maybe your rubbing fender liner =]

 

Are you using the Aux jack? Mine had a whirring from the speakers when I would accelerate while listening to my iPod. There is a TSIB out for it.

 

No it's not the finder liner...

and It can't be the speakers... cause it's stepping on the accelerator not on the speaker! I know how whirring come from the speaksers...

It's something from the engine side or the wheels as I said and if it was the engine engine sign would appear... I wounder what the hell is that sound is...

 

put stock wheels back and see if you still got the same noise... ?

 

hmmm i don't have new tires for my old wheels... I'll try that after checking the wheels bearings

 

A loose or worn drive/compressor belt could make that sort of sound. Same thing happens on my '97 Volvo 960 when I have the AC on; now that I think about it, it could be the compressor clutch.

Leave the car in drive and rev it up..........does it still make the noise while sitting still and not driving it?
