Well I was driving to school then like all of a sudden the car started idling low like really close to zero. Example 1st gear slowing down clutch then neutral then rpms drop. When I accelerate 1000-2500 I hear a whistle like noise or something electric (sound like an electronic toy car)(I think its boost controller) then goes away right after. Not MAF just cleaned it, and i think the blow off valve is stuck open.

Here's a video

Please help thank you in advance

You definitely have a boost/air leak somewhere. What blow off valve is it? I'd check all of you plugged holes shown in the video on your intake tube and well as all couplers just in case. If the BOV is the type that you can recirculate, I would reroute it back into the large port on your intake tube, the car will run better.
