The one remaining part of the fuel system that could be causing the problem is the injectors.
You could try adding a bottle of fuel injector cleaner (Wynn's is good) to your next tank of gas and see if that improves things.
However if your car sat for several months, the injectors could be gummed up and you may need to have them ultrasonically cleaned.
