Exclamation 2010 Accord EX V6 Loss of Compression

Yesterday my daughters Accord had a flashing engine light and VSA light up on the dash. Brought it to have the codes read P0003 #3 cylinder not firing. Removed the spark plug and it was fouled with oil. Compression test noted 90%. Is this a common issue with the V6 engine that anyone has had experience with. Is Honda supporting it in anyway? Looking for help and next steps. Thank you!

Was the code P0303?

Did you pull a spark plug nearby to compare the condition? Was the oil on the ceramic part of the spark plug that the coil pack connects, or on the electrode side?

Did you clean the spark plug and do you still have the code?

Codes were P0420 CAP Effic Below Threshold (Bank 1)
P0303 Cylinder #3 Misfire Detected
P0303 Cylinder #6 Misfire Detected
P0300 Random/Multiple Misfire Detected

Oil was on the electrode side

Replaced with new spark plug, engine running smooth but check engine light still on (not blinking now)

If you have a code reader, clear the codes then post the code(s) that return.
