Bad Plugs?

Hi I just got a 2003 f350 with a 5.4 for work.It was showing a couple codes and I repaired them but the truck is still running rough almost like a couple fouled plugs and stalling at stops.I only took it for a 3 mile ride today at lunch and it acted up in the 3 miles,on sunday I took a 15 mile ride and it started skipping around 7.5 miles and threw a P0720 code ( output speed sensor malfunction)I replaced the sensor before I took it for a ride and reset the computer should I start changing plugs or head in another direction? Any help would be greatly appreciated. Thanks Mike
