new problem with print quality....help!

[ProtoFox]

Ive had my quiditech dual extruder running pretty consistently now for over two months with excellent results. however recently ive been getting these "blobs" on corners (often times little worms that go up and away from print, at a diagonal angle)and sometimes these "loops" on horizontal surfaces. ive slowed down and it seems to help some, but im wondering why this happens all of the sudden......im adding hours to my prints just to overcome this and would rather not. thanks for your input, ill attach pics.......here are my settings on simplify3d:

taulman g-tech
nozzle: 235c
bed: 40
speed: 40mm/s
retraction: 3mm

the image upload feature isnt working.........
