Poor fuel mileage and power

I recently just bought a 2000 323i with some problems but I got it for cheap cause the guy couldn't figure out was wrong with it. When I first start it it will idle perfect for about 5 minutes then it will bog down and almost quit. I can shut it off and start it back up and it clears up for 5 minutes then the same thing. Driving wise it has alot of power until I come to a stop. Then the weird idle comes back and sometimes will shut off. When I take off after it does this it loses alot of power and has a different exhaust tone something similar to a straight piped subaru impreza. Its weird because I can rev it up a couple times and it clears up. Power comes back. Ive put new plugs and coilsensors. New fuel filter. New exhaust and intake camshaft sensors . It was throwing codes for them and oxygen sensors which I haven't changed those yet because I don't see my problem coming from that. Also when I fuel it up u can smell gas bad on the inside of the car. After a couple days the exhaust camshaft code came back on. Im new to this and could really use some help.
