So I recently purchased a 2008 Ford Ranger with 57,000 miles and the 3.0 engine and it has developed a very very small intermittent misfire at idle. More of a rough idle with a occasional hard start. I’ve done spark plugs, wires,coil, fuel filter, air filter, looked for vacuum leaks, chased a white rabbit, you name it. The only thing I haven’t done is fuel pump and intake gaskets.... HELP!!!! PLEASE!!! I love my ranger but it’s behaving badly.
