When you crank the car, it turns over. But when you apply some gas you feel the motor stumbling the whole time, and when you let off the gas it idles at like 200 rpms and eventually dies out. Please help guys, this is getting so frustrating

Im not sure whats going on as its not throwing any codes, also my boost gauge shows no vaccum/boost, what gives??!!
