2.0 Astina strange problem. No power

[Hooligansam]

Hey guys,

Picked up an Astina with the 2.0 V6. Bought it non running and have managed to get it to run just played around with a few things.

With everything the way it should be it will start but as soon as you touch the throttle it will die.

I have disconnected the MAF sensor and now it will rev but only to 2,500rpm before it splutters and backfires (sounds like a limiter).

I am assuming its a vacuum leak. I have included a video to demonstrate the issue. Hoping someone may have insight into a possible cause.
