Issues Idling, Constant Backfire, Loss of Power

So im relativly new to the forums ( been on them before but never made an account )
So i bought a 1986 N/A RX-7 Base Model for $1,500 CDN ) motor didnt have problems at the time but rocker panels are basically non-existant ( i will be fixing them ) but now all of a sudden the motorturns on but wont stay alive and the throttle lags, and backfires similar to a 20-Gauge Shotgun, their is no smoke coming out of the exhaust at all, ( i have a oil leak in my oil pan) And it just idles like garbage, has no power when giving it gas, and backfires every 2 seconds, but turns on every single time you crank it, im confused on this topic, and so are all my freinds, im thinking it could be a few things, my TPS needs to be adjusted/checked for spliced wiring, my MAF needs to be replaced/cleaned, or i have a massive vacuum leak? I have no clue and i have a video which displays what im experiencing for help,

disconnect the TPS and see if it makes a difference

next guess would be low fuel pressure

and a compression test never hurts
