can hear it. It has done this since I have owned it.

I have no codes, very good gas mileage, great power.
I only get the stumble at idle, don't see or feel it at cruise RPM.

Any ideas where to start looking?
Could be a coil pack but you would need to have it hooked up on a scope to see where the irregularity is coming from. Could also be a failing injector.
