I have a 2002 Mercury Villager that has developed a random miss over night. I replace the plugs, wires, distributor cap and rotor button and still misses. Do you have any suggestions?

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
