Extruder fighting itself

Hey I have a standard config 3.1 and after a loose wire in the jst connector I am having extruder trouble. It appears to be skipping steps but after inspection nothing is wrong with the gears. It looks like the coils might be fighting each other because the motor is getting really hot and every few teeth you get a bump in the extrusion and gearbox looks like it's trying to separate. Nothing wrong with the teeth when removing the outer plates. Could the mcu be fried?

Ok it seems that it's related to feed rate. Slower rates there is no issue but standard rates above 10mm/s I believe the filament is jamming and not melting fast enough. This is a Rapido uhf with a bond tech cht 3 hole nozzle. 0.6mm. Is there something happening inside there? I printed pla just fine several times in the calibrations. The I had to rewire, recalibrate, and started on some petg and this happened.
