I'm having the same problem. Recently broke down the extruder head to clear the PTFE tube and reassembled. Now it will not hold temp, swings +/- 7-8 degrees. I ran autotune and uploaded the new PID values (13.11 0.59 72.81) to no effect. Any other suggestions?

1. Did you save the values with M500?
2. Try autotuning again after setting those values, can be an iterative process.
3. Check the resistances of the heater and the thermistor.
