P0300 and P0306
2004 Ranger, 3.0 engine. Above codes are misfire 1st 1,000 rpm and misfire on #6.
Drives fine, but idles a little rough. Prolonged idle causes very rough idle, almost unable to drive. Turn off engine and restart, it runs fine. This makes me think its not mechanical, but electrical or fuel related.
Replaced plugs, wires, air and fuel filter, and inspected/tested coil pack. Reset codes and swapped #2 and #6 at coil pack. Engine ran fine, after a day or so, check engine light came on...misfire still says #6.
Could this be the fuel injector? I've ran Seafoam through the system, but it didn't help.
