Code Po306
I retrieved codes PO306, PO316, and PO1000 today. I change my plugs at 100K and truck drove fine for about 20K miles now it is misfiring again. It would appear that it might be limited to the #6 cylinder. Should I try to change the COP for that plug. That seems to be the simplest thing to do. I have some mechanical skills but these plugs seem difficult to get to in my opinion. Any thoughts would be very helpful.
