Should I just go to a professional....

Was getting a pretty shitty start with rough idling on my 07 530i and codes for my MAF sensor and random misfires in cylinders 3,4,5. Replaced that, cleared the codes and took about an hour, but my "service engine soon" light came back on, but this time it was for my MAP sensor and a random misfire in cylinder 5.... so I replaced that sensor, and resest the ecu. Took about 15 minutes but the light came back on, codes now showing are for low circuit for the new MAF sensor and random misfires in cylinders 4 and 5.....

The car doesn't idle rough at a cold start or when in drive and idling anymore(so far), but wondering if I need to get my sparkplugs and ignition coils checked....

Any ideas?
