95 lt1 wont idle ,need help diagnosing problem

[mmracecars]

Have a 95 that i put a procharger set-up on,with new opti,plugs,wires,
.car ran great for a month,drove it every day,then all of a sudden it wont stay
idling.it runs great for a minute then either stalls or almost stalls,then goes back to running and continues to repeat this.It does it in both open and closed loop(but worse in closed).i have a program on my lap top that i can look at all the parameters when its running,and nothing looks wrong to me.so im not sure what to do next.any suggestions
would be appreciated.my first guess would be MAF sensor.

What do you think it's the MAF sensor? Can you see the airflow while it's running? What program are you running? DataMaster?

Brian,this is actually in my vette,it was running fine,then i disconnected the maf to move it and the air cleaner a little bit ,then this started happening.so im just guessing on the maf.i have the datamaster program but im still trying to figure out how to get it to work.im using a free scanner program called pcmcom,icn look at all the sensors,everything looks ok and no codes.do you know if steve is still at vector motorsports there right across the street from my house,he tuned my procharged 93 camaro last year.
thanks
