2001 Blazer problem

[hardrock2401 8]

There are no vacuum leaks and the timing is good...I pull code p0102 (maf sensor) and sometimes a p0305 (cyl 5 miss). The truck stumbles from idle to about 1k rpm when in neutral or park. I tried cleaning the maf and disconnecting it, either way it ran no different. The plugs, wires, cap, rotor, and coil are all new. Any more pointers from anyone, could a bad maf cause a miss?

Check injectors?

The mass air meter measures all incoming air. If it's not working properly, of course it could cause a miss. Check all the connections as well for corrosion and broken wires.
