So, whenever i have prints that are not a solid infill, at the layer the infill starts the outer perimeter looks messy. If the item is solid then it's fine looking.

It happens for 2-4 layers then clears up. It's not the bottom most layers but as I mentioned seems to start when infill kicks in. This is printing in ABS on my TAZ 4 with a .35mm nozzle. Since Simplify3D did not come with any presets for the TAZ 4, I started with the TAZ 3 settings then modified them a little to work. I have also included photos of the condition and my settings for layer & infill

The Taz 4 and Taz-3 are extremely similar. I think that your problem is cooling. Under the cooling tab of the FFF setting, try changing the values to

Adjust printing speed for layers below: 20 seconds
Allow speed reductions down to 15%

these layers took a good 45 seconds or more so I don't think it's cooling. I have this same problem on items that I gang 10 up so it takes 5 minutes a layer and it still shows this.

I think I fixed it. I changed infill / outline overlap % from 15% to 6% and at least the last few models look good.
