My car has a high pitched whistle noise while i give it about 1/2 throttle in any gear, then it will go away. I have checked for vac leaks, cleaned the MAF and throttle body, put in a new pcv valve, new air filter, and the new intake gasket seems to be in place. I actually have more vacuum pressure then i did before i pulled my motor out. Just wondering if anyone has experienced this before, or have any input? Thanks in advance!
I get a slight whistle when I give the car a decent amount of throttle. My whistle is one of my pulleys making some noise, I think it my be the AC delete pulley. I replaced the baring in the pulley but it still makes some noise.
Its weird because its didnt do this before i pulled my motor out. The only things i changed on my motor was the AC delete(one that moves the PS pump up) underdrive pullies, egr and emission delete.
Gonna start driving into any hittable object or human if I cant track this down. It sucks that it wont do it when i rev the motor when its parked, only when i'm driving. Its like a high pitched squeal that you would think was someone blowing a whistle in your ears. Its only at certain throttle positions. Ive checked for vac leaks, cleaned MAF/Throttle body, new air filter, new PCV, new IAC, re-tightened connections, checked gaskets. Any other suggestions?
Ya im gonna try running up the street real quick after work with the belt off. Ya and all the grommets are back in by the hood, but defintely a good call on thinkin that.
if you have a throttle body 70mm or bigger your gonna hear a whistle its just the air coming in its sick you should like it theres nothing wrong they all do it

my car whistles too but i got a turbonetics turbo makin that noise. but ive heard the noise your talkin about some throttle bodies make that noise like someone said above def can get annoying
Ya it has a 70mm throttle body with a 73mm MAF. The only funny thing is that it didnt whistle like this before i took my motor out. Thats why I am baffled. You'd have to go for a ride in my car to listen to this whistle. Its so weird.
P.S. I only wish it was the culprit of this whistle was a turbo lol
