is it the way the intake manifold is made or what, at a certain throttle level it makes a grasshopper noise, hella anoying.

 

title made me think of china farmers from wow. haha anyway. Do you have an intake on ? somtimes air going through the TB makes some funny noises.

 

mine did it because my clamp was a little loose

 

probably because someone adjusted the idle screw without unplugging the eacv first.. iv done it and got the wistle. adjusted the idle the right way and its gone... its because you close the screw so far down.

Correct, back off your idle adjust screw a tad and it will go away.

 

i had the same problem and i fixed the idle screw as well and everything sounded good but all throttle bodys might whistle depending on what gear/and mph your going just because the butterfly will be open and when air rushes in it is just like you whistling with your mouth but this problem is more prone to happen on a car with aftermarket intake.

 

That whistle used to drive me crazy whenever my CRX was running

I never could figure out what it was, but I did do alot of adjusting on the TB. I guess thats why...

 

My DOHC ZC CRX and friend's CRX with D15b (both have AEM CAI) make a weird whistling sound at certain load/RPM. Doesn't really bother me.

 

Yea that fixed it, i remeber when i had an obd1 conversion we adjusted the idle screw becus the car was acting funny, and i guess thats where it came from, now i dont go crazy everytime i hold it at a certain level. thanks

 

make sure you adjust the idle correctly ... search it. you have to unplug the eacv before touching the idle screw.

 

haha, thats funny. I always wondered why my friends rex did that.

 

It's not a unique occurance with the CRX. My stock S2000 does it too. Sure it's quiet but you can still hear it.

 

because they are happy.
