Hello everybody,
I’m brand new to the forum. Looking for some tips or advice on my truck. I have a 2004 Ford Ranger Edge with a 3.0liter V6. My truck throws codes p0305 and p0316 after about 2-3 hours of driving. I know p0305 is misfire on cylinder 5 and p0316 is the first 1000 revolutions. You can Pull over into a parking lot or stop at s drive thru after the long drive etc and you’ll start to notice it start running rough and shaking then the check engine light starts flashing(which throws the cows p0305 and p0316). You Start driving again and the check engine will go to a stay lit check engine lit not flashing then go away. Driving it seems to make the misfire and rough idle ands shaking go away. Letting it sit for a day or two when it’s misfiring with the check engine light on will also make the check engine light go off and misfire go away and run fine. The spark plugs were changed 4000-5000 miles ago. I changed out the ignition coil pack and it still does it. It only does after long drives. Commute around town and the misfire check engine light doesn’t come on , no misfire and runs fine but a few times it’ll start have a rough idle at a stop light but it’ll go away and a check engine light will never come on. Anybody know what might be causing this or has had a similar problem?
