It started off with running too lean and air mass too high. I had planned on changing the chargepipe. It would rough idle on cold start and today codes P0133 & P0111 came up. So I'm wondering what should my next steps be... new O2, MAF & MAP sensors?

*Only thing I've done to it is CTS cold air intake

Check for loose connections. Make sure your MAF and MAP sensors are seated and electrical connections aren’t lose. If you don’t find anything out your stock intake back on and see if the codes and rough idle go away.
