P308 code Dodge 5.2

According to some sites on the internet, P308 means that the #8 spark plug isn't firing correctly but the engine seems to be running smoothly. Any ideas?

Edit. I did a hard reset on the computer & the light went out.

What year is your dodge? The hard reset you did got the MIL to turn off, but getting the MIL to turn off is not a repair. You still have a misfire at the number 8 cylinder. The misfire could be an ignition misfire (and or) a cylinder misfire. Are the sparks plugs and ignition cables due or long overdue to be replaced?

Thank You
