Rough idle at stop - common or in my mind?

[Burby]

When on a flat grade at a stop light and holding with the brake I can feel a slight engine bobble now and again. It is not a lot but definitely rough enough to notice. I've got around 17K miles and just noticed this.

Kind of visually feels like this - _________---________-----__________----_______

Not to be picky but this was smooth before and now starting to act up. Might try disconnecting the battery to reset and see if that helps.

Try different gas. 87 octane. Detergent gas from major brand. Couple of tank fulls
