sound from tb
theres a whistling sound coming from my throttle body/intake area. Im 90% sure its the throttle body. It does it at idle, when i rev past say 1500 rpms it goes away. Any ideas? I heard it could be from the throttle plate not closing all the way. how can i adjust it? could that cause Hp loss?

RE: sound from tb
if you have an aftermarket intake, then it's normal
if you don't, then there's an air leak |
RE: sound from tb
i have an aftermarket sri but it even makes the noise with the intake off.... plus it made it with the stock airbox connected. i know the sound of sris and cais thats not what this is

RE: sound from tb
well, the throttle body makes that noise on it's own. that's why the oem stock air box is so quiet because of it's size and the plastic material soaks the vibration from the noise. sri's and cai's are usually made from aluminum, which doesn't soak the sounds as much, plus it's less restrictive making for higher pitched noises to be heard.

RE: sound from tb
you must have misunderstood. It did make the same sound with the stock airbox connected.
plus if you tap on the top of the throttle body you can hear a slight rattle sound... and when i get into higher rpms theres a very loud rattle which im thinking is the throttle body. |
RE: sound from tb
is your throttle cable loose, or is the butterfly swivel loose?
|
RE: sound from tb
im pretty sure its the butterfly. but the wierd thing is i still idle around 750-800 once its warm. but during the warm up she bounces around.

RE: sound from tb
Mine whistled when I put the stock box back on last winter... and I discovered that I hadn't plugged a sensor in...
|
RE: sound from tb
all my sensors are plugged in everything together i think its a prob with the throttle body itself.... is there anything i can do to fix it? what would it take to *overhaul* it? i guess thats how i should put it but can i do anything by taking it apart? maybe adjust the butterfly or anything?
