Temp Fluctuations - thermistor or hot end?

I was getting a lot of temp errors and other misbehavior, so I backdated firmware to 3.11 and that solved that.

However, now when I print, the nozzle temp is all over the place.  Set at 215 it can go from 190 to 230.  Sometimes jumps 2-3 degrees at a time.  I know that it's actually overheating because my PLA just drips out.

Is this the thermistor failing, or the hot end itself?

Thanks.

It *might* just be a loose connection or cracked wire - check these before doing anything drastic.

Cheerio,
