Please Help! #3 Misfire

Ok, I have a 2001 ford ranger 4x4 with a V6 4.0L Engine. I am getting a cylinder #3 misfire, I have a new fuel pump, new fuel filter, new plugs and wires and coil pack as of 1 month ago. Heres how it happened in order.. I started it in the morning and it wouldnt even get out of the driveway I had 3 total misfires.. Then I went back to look at it 4 hours later and let it run. It started running much better and seemed to clear itself out. I found this very odd. I got the code checked again and now I only have one misfire on cylinder #3.. It comes and goes, and it mostly happens during idle rpm or below 1,000rpm's.. Its very bad sometimes, and very slight sometimes, and sometimes its never there at all.. I ran lucas fuel injection cleaner through it with no luck.. Any suggestions?
