Whenever I step on the pedal a bit and the needle goes past 3, my 99 GS makes a whistling noise. Nothing really happens, it just whistles from the engine. I don't know if that's good or bad. And my mechanic said he'll charge me to do a maintenance check on it, so I said no. Anyone know what it is?

 

my old RS did that too, people at first thought it was a turbo in my car, but told em it was just a noise. i think it normal for the 420a but im not sure.

 

i think it to, my rs used to do the same thing

 

Check all of your vacuum lines, escpecialy the ones on the intake mani. They tend to crack.

 

Its just the intake

 

mine does that whistling as well. oh and my friends eclipse did it too, both 420a's but i do have a crack on my intake.

 

So...chances are I have a crack in my intake?

 

not necessarily, i had an aftermarket intake that was fine, but it still whistled... i think its just a designer flaw or something

 

Its not a damn designer flaw lol. I hear this EVERY DAY with n/a cars. More so in high flowing intakes. There is a guy with an RSX Type-S down my street and I hear him every morning.

 

i think it actually sounds kinda cool. but doesnt really sound to healthy for the engine...

do you think it would make a loss in power?
