Yes. That. Take the bobbin case apart and clean the fuzzies out of it, then - since your upper tension is built back to spec presumably - set it tight enough that it stitches out nicely at about 4 on the upper tension. I'd post links but they always get edited out anyway. Follow the video link Miriam posted and follow it to the site. There's tons of information on tension there. I guess someone has a little stress in her life.
