So I get back in the car to go home from my girlfriends house about... thirty minutes ago now. I crank it, it fires up... and it's making a whistling noise. And the idle is all squirrely... it held at about 1200RPM for thirty seconds and then started slowly coming down to around 750RPM... still making the whistling sound. At first I freaked and thought it was the rear end but then I realized the car was still in park and nothing back there was turning...

Next thought... IAC (because of the stumbly idle) or the AIR pump. My mechanic told me the AIR pump was on the way out (screw pollution controls, right?) so I didn't know if maybe that was the noise.

Anybody have any clue? This is a 305.

 

Sounds like a simple vacum leak. Check all your lines/hoses, and spray some carb cleaner around the intake area... if the idle changes, youve found your leak!

 

any of your belts come loose?? or mis allighed?

 

I just got back from Goodyear... they looked it over and told me the bearing in the alternator has gone bad and that's whats causing the whistling. $180 installed for the new one... driveable, but if the bearing seizes i'm stuck. It's still charging and everything... blah. I just laid down $400 for seats and $200 for a new console. Pfft. Car's getting spoiled.
