HFM Code 21 95 E320

Have been gone for about a week.

Started the car up yesterday and it is running very, very rough. I have a code 21 on the HFM which Alldata says is
"ignition output 3 or ignition coil".

Just put new coils in about 6 months ago.

Any suggestions as to how to troubleshoot this will be appreciated.
