Cr-10s quality issues

[BaramE20]

I am using my cr-10 and having very interesting results. I am having awful prints with scattered holes in them. I try to print at 100 percent infil and prints still look like a sponge. U can break prints effortlessly. At first I thought it was a major filament jam, but I do not thing so. That leaves with the extruder? Please let me know! I am out of ideas

Partial clog. Either use guitar string or cold pull methods to clean it.
