Engine started running rough today and checked for a code and it was P2308 ignition coil c secondary circuit. Does this mean that the coil is bad?

Not necessarily a bad coil.


P2308-IGNITION COIL 3 SECONDARY CIRCUIT- INSUFFICIENT IONIZATION

• Set Condition: If PCM detects that the secondary ignition burn time is incorrect, too short, or not present, an error is detected. One Trip Fault. Three good trips to turn off the MIL.
