As the title states. 2004 3.0L starts up fine and runs , but runs rough through all rpms while driving but still pulls and idle is a bit rough. It started to do it as the weather went from below freezing to above. Did it a few times and went away shortly after. I changed the air filter and the plug wires as i saw them arcing a bit. Thought it fixed the prob cuz it was fine for a day or two. Now it does this all the time and I can't find the problem. Changed the plugs cuz i thought it could be that, but nuthin. The old plugs looked fouled with fuel but in decent shape otherwise. It did throw a code but only when I put in 3 when i shoulda been in 2 , 4 when i shoulda been in 3 making it lug. I dissconnected the battery for a while and now no check light but still the same problem. It would really buck. Any help would be greatly appreciated
