I use stethoscope (no stick, kind of like medical one) to find vacuum leaks and found a few air sucking sound sources around throttle body area.
Any common vac. leaks?
Thanks.

Given the age of your car, suspect every rubber hose and seal on the intake. breather hoses, the brake booster hose, the T-hose on the throttle body, and seals around the MAF sensor - all suspect. I just replaced them all on mine.
