2009 Ram 1500 misfire

[924Ram1500]

I have a 2009 Ram 1500 with a 5.7 hemi that has 103000 miles. I have a multiple cylinder misfire code. The truck seems to be running fine, any ideas on where to start? Thanks

when was the last time you changed the spark plugs?

Coils, boots, plugs, wiring, injectors & PCM if you want to shotgun parts at it. If not, your going to need a friend or tech that has a good scan tool to monitor the misfire events and deduce what is wrong by what is not wrong.

If this was a single misfire, would be way easier.

Edit: Since you mention it seems to run fine regardless, I would lean on plugs and the rubber coil boots being degraded and allowing leakage.

Is the CEL steady or flashing?
