I put my scanner on the car and it said misfire cylinder 2 so I changed all the spark plugs, then I changed the coil, then I changed the injector but it still says misfire cylinder 2, I'm thinking maybe the valve but not sure.can you give me some advice on this please.

Why didn't you list the mileage? If this is a high-mileage engine, you might consider performing a cylinder leakage test to see compression is leaking out, and where. Another potential cause is a worn lobe on the camshaft.

This is from Mitchell OnDemand online service manuals.

I think 120 pounds is okay. It's more important that it be close to the same on all cylinders.
