well, i was driving home today on the highway and noticed that when decelerating in 5th, right around 2500-3500 rpms, my bov would make a wheezing/whistling sound. i have a k&n drop in and this is the first time my car's made a noise like this. is it maybe beacuse of the insanely cold weather tonight? i didn't really get a chance to check the hoses becuase it was dark out and really really really frickin cold, haha.

 

its not the chirp sound ?

 

well, i had the chirp sound before and know what it's like. this was more like a wheezing/whistle... if that even really makes sense. when i slowed down to local roads, the noise was less apparent and went back to the usual chirpish sound.

 

my guess is the cold effects the piston travel
post up how it sounds tomorrow and what outside temp
