Yeah, I replaced mine, still hear the same "turbo" sounds

 

i know this is a old thread but does anyone have an answer to this mines doing it too

 

Doing what? Unstable idle? Could be a vacuum leak, (possible blown plenum) bad TPS, or IAC.

 

i just replaced my plenum gasket and intake gasket and cleaned the iac and a shop checked all my vacuum lines and they all checked out ok, its making a whistling noise only when i accelerate and it doesn't seem to have the power it should when i accelerate. its also burning oil somewhere, it doesn't leak it just burns it out the exhaust that i haven't found yet. tested my head gaskets and they were good

 

im from adrian, mi to by the way

 

If it will do it sitting still, grab a friend, and go lookin'.

Welcome to DF.

Ah, adrian, the armpit of michigan. I actually live out by clayton now. Just haven't bothered to change my profile.

 

every time you hit the gas it will do it, i look for hours yesterday and came up with nothing just sounds like the top of the engine somewhere, ill look more today

 

id label adrian more around the crack area just below the tramp stamp lol. i lived in clayton for a while too i grew up in and went to sand creek high school

 

It reads like one of the intake manifold gaskets is leaking, you might just have to redo the gaskets. Was a comp test done before this work was? If not do one now just so you know what shape the motor is in.

 

I was trying to be polite.

Grab a can of carb cleaner. Let the engine idle, and spray anywhere there is a gasket. If idle changes, there is your leak. Keep in mind, I don't think carb cleaner is as flammable as it once was, so, idle should go DOWN when you find a leak.
