The compression is as follows:

1) 60 psi
2) 90 psi
3) 100 psi
4) 75 psi
5) 20 psi
6) 0 psi
7) 30 psi
8) 60 psi

After putting a few squirts of oil into the cylinders to check for ring leaks, the compression was:

1) 122 psi
2) 105 psi
3) 100 psi
4) 120 psi
5) 30 psi
6) 0 psi
7) 95 psi
8) 118 psi

I also am throwing codes P0300, P0346, P0305, P0306

Almost no power
I replaced the coils and plugs all the way around

Any ideas other than faulty rings?

Thanks in advance!

 

Also, idle is rough and there is a loud whacking sound when it is first started, subsides after a few loud bangs, and goes away on subsequent starts.
