2002 Ranger 3.0 6 cyl. I'm not a mechanic, I'm a parts changer extraordinaire. Need help on this one. I have a severe miss cylinder 4 mostly, but 6, 3, 5 pops up from time to time as well. Changed: All Plugs All Plug Wires Coil Pack (twice) All Injectors PCV Valve MAF Sensor cleaned Checked for Vac leaks Replaced vac lines. Fuel Filter few times Any direction you can point me in would be great...I own a food truck in Pcola FL. Right answer will eat free for the rest of your Life.
