PO352 ignition coil B primary/secondary malfunction

hey all,
keep getting this code tripped,( po352) have changed the coil, but still have this problem, however it isn't a constant problem!, you can feel the engine smooth out and run fine the majority of the time. i'm thinking maybe the spark plug might be fouled ?
any help would be appreciated

yup! it was a faulty spark plug, the porcelin center was moving up and down inside the metal thread/nut piece. $ 2.99 for a new spark plug and now i have a spare coil as well
the parts guys said they've never seen one do that before!
it was an autolite plug too
