Sounds like you have a injector issue. Keep a eye on oil level, if it's climbing it needs fixin now.

Mine would miss at highway speeds. If I stepped on the throttle it would go away. My wife said it was like a woof.

Suggestions:

Clean MAP sensor
Clean EBP sensor and tube
Clean EGR valve.
Check FICM voltage readings

I did all those and didn't notice much of a change. But, it's good place to start before throwing parts at her.

Bought new EGR valve, hasn't done it since.

It was worse when I was towing.
