CEL! Great... P0300-P0306/ P0174/ P0171 Help please...

So heres the background on my car
It's a 04 Z4 2.5
Has 114k miles on it. I just changed the spark plugs to NKG laser platinums since 3/5/6 were misfiring. Now all of them seem to be misfiring. ( and I just changed ignition coil 4 a couple of months ago )
I also just cleaned my MAF but that code seems to still be there after I cleaned the sensor with CRC.
The car doesnt really idle too bad at all, just a slight 850 and moves to about 900 rpm's and no big jumps.
It does make an odd new whistle noise a bit in 1st and 2nd gear and I can sometimes hear it when idle since the CEL came on. I've heard that the DISA on the vehicle is a common issue. Any tips or advice would be greatly appreciated.
