BUCKING WHEN TURBO KICKS IN WHEN ENGINE IS H

1995 SAAB 9000

Engine Mechanical problem
1995 Saab 9000 4 cyl Front Wheel Drive Automatic 180000 miles

when I first start car and take off no problems but when car warms up and I accelerate I watch my turbo gauge needle bounce back and forth as the car takes off and then hesitates and takes off and sometimes it bucks. I read that this may be the mass air flow or the apc solenoid due to over boosting it cuts off the fuel pump. I am not a wealthy guy and cant afford to take to repair shop due to many kids lol. I am a mechaniclly inclined and can handle most repairs I am just stumped. It doesnt appear to have a vaccum leak and the check engine light is not on. Is it vapor locking? Is it the apc, is it the mass air flow sencor or an o2 sensor. Please help this is my family car
