my 8 is dumping to much fuel

i really dont know where to start but a day or two ago my RX-8 started running PIG rich at idle...the cobbs afr was reading 11-12afr range....during cruising whenever i let off the gas you can here huge pops and flames coming out the exhaust....but when i floor the car it has crap tons of power i kept up with a new STI for crying out loud but all this is weird.....i cant seem to wrap my head around idk if the car needs to be tuned or if there is something seriously wrong like a injector related issue. i did use the BHR dwell table to adjust the dwell settings in ATR from on this thread https://www.rx8club.com/series-i-eng...0/#post4366152 and it was fine for 2 days... but for some reason the car just started running super rich...
