Running Rough - 2k Limited 5.0L V8, 143k miles

Here's a 30 sec video. Runs very rough and smells bad. The only diagnosing I've done is looked at some data using DashCommand. No CEL and no codes. It is showing some misfires. Post-cat O2 voltages are both near zero.



Any suggestions are greatly appreciated.

Replaced ignition coils and that fixed it!

The coils are so easy to replace on this model, I took a chance - whew! Glad I didn't have to spend tons of time tracking it down!
