My 2003 sonoma makes a loud wining noise when i step on the gas, but disapers when i take my foot off the gas

If it accelerates OK and nothing else seems wrong I wouldn't worry about it because it is probably just changes in the air flow volume through the air-intake system causing this whine!!

Some whirling noises

suspect it is warped disc rotors. If the pedal pulsates under your foot on light braking I would take it to a brake shop for investigation of the fault. Any noise or unusual incidents with brakes can become critical if ignored.

If the noise is just a spinning sound and not a grinding, than you're starter solinoid is probably bad.
You're best bet is to replace the starter. Hope this helps.

1999 Saab 9-5 SE

I own a  99' 9-5 V6 turbo SE.  Had the same thing.  Started smelling gas in the car, sometimes.  Instead of not starting it died (as in the engine stopped) on a barren stretch of road at night.  Towed to the Saab dealer: Conclusion?  Replaced the fuel pump and sending unit. Don't ask how much.
