Check Engine Light check Engine Electronics

I have a 1997 E320 with 116,000 miles. The check engine light came on with check engine electronics. The engine has a rough idle. The owners manual said it is the fuel injection. Is there any thing I can do to replace the bad parts

An OPD 11 code of PO304 was read. It means a misfire in cylinder 4.

I checked my maintenance records and noticed that my spark plugs were changed Jan 2007.I had the plugs and coils changed and the car runs great. I don't drive the car 5,000 miles a year.

We do have diesel section here for diesel.
I am not aware diesels have knock sensors, but technology surprised me more than once.
