Hey,
I have a 2012 Honda Civic Ex Coupe with 194k miles, and recently I noticed that I have misfires on the engine. They are minimal, but they are still there. I drove to New Hamshire (about 150 miles) and had only like 50 misfires in total. The car starts up and drives completely fine, even cold starts smooth and fast. I have been told by multiple people that it's not a problem, but I am sure that misfires are always supposed to be zero. Note - That there are no Codes in the scanner or Check Engine lights.
To diagnose, I have changed the Ignition Coils and Spark Plus, but the misfires still remain the same. I have noticed that the car never misfires in idle though (according to the scanner). I can't feel the misfires at all. I have also checked the battery at an AutoZone and it is also in great shape.
The Misfires are divided among all the cylinders. I drive it to and from school daily, so wouldn't want it to have more problems in the future.
If you are in Rhode Island, maybe I can bring it to your place someday(I am in Storrs, Connecticut). I'd love it if you'd show it on your channel.
I am attaching a screenshot of the Total Misfires screen (after driving 10 mins) 
Thanks.
From the above page -
I have isolated the spark plugs and the ignition coil out from the equation. There was no fuel on the old spark plus when I changed it, the ignition coils had some marks of wear (probably because of the 194k miles) - but they worked fine. I changed them because I got a good deal.
I have checked the air filter and it was fine, changed it 1k miles ago. This is the stuff I could do myself.
For checking compression, I don't have the tools and I'm quite scared to do it, the same goes for the vacuum test. I have visually inspected the lines though. They look old, but I don't see any cracks or leaks(at least visually).
Can we make a more targeted diagnosis using the OBD2 data, if yes, what am I looking for?
I would attach the OBD2 Scan data, but the anyscan a30 mobile app doesn't allow to export the recorded data.
ALso, I think the misfires occur when the engine is decelerating from a high rpm. I might be wrong and this might simply be due to the delay between the phone and the obd 2 scanner.
It would really help if someone could tell me what exactly am I looking for in the obd2 data.
Well, the compression tests and vacuum test are important. For obd data, you need to find out under what conditions the misfire happens and since you don't have a check engine light (I assume), it is not that easy.
That's the thing, I don't have an engine light. been driving for over a month with it. I believe that they occur in high RPMs, either while accelerating, or decelerating.
