FORD F-150 CHECK ENGINE LIGHT PROBLEM

2003 Ford F-150 • 104,000 miles

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.

Is the check engine light on?

How old are the spark plugs?

Check the intake manifold for leaking coolant into the coil boots
