When you say "codes" do you mean with, or with-out a "check engine light"? You can have codes and NEVER get a "check engine light". I think that almost everything on the list can happen and not activate the check engine light. probably most of them could even happen and not throw a code initially. Most of them will
eventually cause enough issues that a code will be thrown.
Not sure that helps, but at least check for leaks and make sure your filters are all good. Then make sure the oil is good (if you have a bad injector and fuel is leaking into the oil it can cause problems) - I like to take a sample and send it to Blackstone for oil analysis. then check out the wire chaffing links.
Post back if and when you have gone through these.
Sorry it is so complicated, but such is the beast .....
