The finish of my prints is ugly

When I print something I always have an ugly finish on the vertical parts of the prints. I don't know which parameters I can change. I already to over extrude or under extrude. But it change nothing. The photos is actually a print with abs. Bed 100° nozzle 240°.

What speed are you printing at? 240 may be a little on the low side for ABS unless you are printing slowly. (slow is relative these days 😂) Also, how much cooling is there? Kind of looks like the odd layer is warping and not properly joining to the previous one.
