I have a 2001 4700 international DT466E my problem is that when it sets for a while and then we drive it the engine light comes on and then it starts sputtering and missing. When it sets idling it will start to sputter and sound like its running out of fuel. It also surges when we are driving it. We changed the accelarator pedel, air filter, fuel filter today. Yet we are still having the same problem. Any suggestions on what it could be causing this?
