Cylinders are fine.
The hose ii question is under the filter by the firewall on the right side near the fender. It's like a canister with two hoses on top (one of those is from the fuel tank), and one single hose from the very bottom. This hose was not connected to anything and appears to be some kind of drain hose.
I believe I found the problem. The vehicle has been sitting for months. Driven very seldom. I got some STP water remover and injector cleaner and put it into the fuel tank. After a few minutes and some rough reving up, the engine smoothed out and seems to be running fine. I still have no idea what that hose is for on the bottom of the filter.
I can take a picture of it and send it to you!
