z4 service engine soon issue

Hey guys, so my 2003 z4 was running great until last week when the check engine light came on and the car rpms started hesitating. I plugged in the code reader and got 7 CODES!!

The codes are:
P0171
P0305
P0313
P0174
P0306
P0304
P0300

4 of the codes are cylinder misfires so maybe coil issues but why would all 4 just come on at the same time? This is really perplexing and I dont know what it could be. If anyone had a similar issue I would love to get their input.
