Hi guys, I have a problem that I hope you can help me figure out. I have an 04 Ranger, 3.0 2wd standard 5 speed. My problem is that a couple of weeks ago, I noticed that when I start out in 2nd gear the engine spits and sputters, but once the rpms come up a bit, it runs fine. Also, my idle is around 500 and rough, but it has always been that way. Was told by Ford that that is normal. This spitting and sputtering is NEW! What could it be? Changed plug wires and coil. Plugs are newer, so should not be them. I suspect the Catalytic converter. HELP! PLEASE!
