I just picked up a bad esn sprint phone. Its pure stock, locked bootloader and all. I did a couple factory resets. And cant for the life of me figure out whats causing the lag. For a minute or two after boot its tolerable app drawer speed but whenever I open something (any app at all) it will hang anywhere from 5-30 seconds. Then once the app opens it will hang up again. Sometimes popping up the not responding wait or force close box. I hit wait and almost instantly its useable but laggy. Anyone have any ideas

Backup your stuff. Unlock bootloader. Flash factory image. Report back if it solves the problem.

No working pc at the moment. And why should you need to reflash the image on a factory unrooted device. It seems after i clear memory with clean master it speeds right up again for 15-20 minutes. It gets down to 11% available memory. I don't have really anything installed except xda and some tools. My hope for this phone is to try and learn how to port a ROM and want this phone to run smooth pure stock before i start so if it has a lag when i port i will know its my fault. And when flashing stock image can i downgrade without any issues

Factory images are one of the best sources to start afresh. Flashing a factory image (4.1.2 in this case) will wipe EVERYTHING and you will be able check if the lag is still present.

And since, you are working on porting a new ROM which I thing is > 4.1.2, you will not face any downgrading issues.
