The P1131 code is lean bank one and P1152 which is bank 2 running rich, so this is because on bank 2 the system is running rich so the computer tries to lean it down to be within limits, but it can't, so it goes to lean and bank one is affected. So, on Bank 2 you have an injector that is stuck open or dirty, to find out which one pulls the plugs on bank 2 and one of the plugs will be dark/black this is the cylinder that needs a new injector, (and spark plug).
Here is a video on how to change the injector out:
