Keep taking my engine management light off but it keeps coming back on after about a week or so, is this cus of the Decat or another problem?

Yes it will keep coming back on. As long as it thinks there's a fault, it'll keep telling you there is one, no matter how many times you put the light out.

One solution is - put the light out, take the post cat lambda sensor out and tie it up under the car somewhere so it's reading clean air, plug the hole in the decat with a suitable bolt.
