    The new ranger (3.0) runs great !!! Except it has a little miss to her lol...
    Things I have done already ,
    Spark plugs, wires, coil pack, air filter, cleaned maf, cleaned throttle body ...
    There's no codes and from what I can tell there is no vacuum leak , any clue ?

    Could just be a rough runner. Pretty much any Ranger I've driven or owned or rode in ran a little on the rough side. Smoothest one was a '01 2.5L. lol. My '06 4.0 in my '01 is pretty not smooth. lol.
  6. Same with mine. Put new plugs and a gently used coil pack in from Hooligan and it still idles rough slightly.

    could be bad headgasket too, leaking into cylinder will do that. my grandpa had a 99 with 3.0 and replaced stuff like you did and that was the problem.
    you can throw some "bars leak" in there, but its kinda half ass way, thats some nice stuff going through your whole cooling system ha...
