This is preety new model,but still i won't rule out the spark plug on that cylinder.Run your vehicle in dark with hood open .See for any sparking on ignition wires on that or any other cylinder.If you find any replace the ignition wires.You should not rule out the ignition coilpack ,try cleaning it for any residue on it.Well there are too many things that can cause a misfire .If this would not fix the problem you should check for any vacuum hose leak.Ther is the diagram for vacuum hose on your van hood.refer it.Last would be the fuel injector on that cylinder(for 2003 model well it depends on your mileage).Go to "mr lube" kind of shop and get your injectors cleaned.After all this i can just wish you good luck. In my 98, I was getting misfires while cruising (but not at idle) because of a defect EGR sensor! Talk about B.S. That was causing FOUR computer codes (engine misfire, mixture too lean, EGR excessive and EGR insufficient) My Experience== I've had the check engine light come on and diagnostic codes for misfires occur for the following reasons: 1. Check or replace plugs and plug wires 2. Ingnition coil (there's 2) going bad 3. Vacuum leak which messes up the air flow. There is definitely a defect in the air intake which has tech service bulletins out on it. The seals go bad and need replaced which requires removing upper and lower air intake manifolds and replacing seals and bolts.
