crazy whistle and bad idle

[Drifte]

my car idles bad, i hooked up a logger and it says i have a bad intake temp sensor, and a bad speed sensor. When i rev my car its normal, then on the way back down i get a whine/whistle noise. I thought it was my turbo but, i stuck a pipe and a muffler on today,(temporary) and i can hear the whine, its near the cams. maybe the crack in my manifold has something to do with it...idk.

Maybe with so much air escaping it make a whistling sound.

I have a whistle, it sounds like a rusty see saw. I was told that the bypass valve created the noise.

definatly not my bov, at first we thought i tmust be my alternator bearings, but thats now it. any other ideas?

are you missing your biss?

If he missed his biss, his idle would be completely out of wack.

when mine dissapeared it ran for like 10 minutes till it died at idle. I know this cuz i noticed the very bad idle. I was able to make it home. But that was a stab at the problem. Can't say i didn't try.
