Sounds ignition-related. A misfire will sometimes seem to smooth out at higher RPM's but is always rough at idle. What kind of plugs, wires, etc did you use? where did you get it? is it gapped correctly? is the rotor on properly? Are the wires going to the right cylinders?

I also replaced the fuel filter and fuel pump. The rumble idle isn't something I remember before replacing all this stuff.
