I've only had this truck about 6 months. Truck has had a rough idle since I bought it. Just recently it has started to miss when driving, idling and under acceleration. Does'nt happen all the time. The dealer I purchased it from changed one of the COP before I bought it because it ran really rough. It has a 4.6.
have the same problem?

Is the check engine light on?
How old are the spark plugs?
Check the intake manifold for leaking coolant into the coil boots
