160 codes after changing spark plugs and coils

So I just did valve cover gaskets ignition coils and spark plugs on my 2007 Hyundai Sonata 3.3. When I put it all together, it won't start. It is throwing 160 codes. I took it all back apart and then put it back together. It is still having the same problem. Hopefully this happened to somebody else and they know exactly what it is.
