Back firing through the intake

Back firing through the intake
So my truck is running terrible, just no power what so ever. I put a vacuum gauge on it and it pulls a steady 14hg while idleing and around 10 hg with the throttle half open, but as soon as i crack the trottle the vacuum goes to 0 and the engine almost goes dead like it choking out then the RPM start to rise like they should. If i crack the throttle and close it quickly it backfires throught the intake. Anybody have any suggestions?
