We all read misfire threads nearly every day. Something I am trying to figure out is with my own understanding of what is a misfire.
Now, I know what a misfire is. What I don't understand is the "I got a misfire but no codes" statements. "I clearly have a misfire" or "My car misfires at idle then it goes away", yet they are not accompanied by misfire codes.
I don't think a poorly running engine, or rough idle automatically equals an undocumented misfire. Just because my car is running like Sh$t, do I get to call it a misfire every-damn-time?
Or, do I need to change my perception and we all do indeed suffer from legit misfires the ECU doesn't care about?
What do you think?
