The truck has had the check engine light on for a long time but was running fine. Now the idle is rough, it runs rough, the gas mileage is very poor. We have changed the spark plugs, changed the oil, changed the fuel filter nothing had made the light go off and all other problems listed continue to be problems. I think the code refers to the crank position sensor but want to ensure this is the actual problem before replacing it. Thank you for and assistance you can give me in this matter.
