Have radiator cleaned, bay bed part blocked in the cores restricting circulation, not just a back flush but a full clean by a radiator repairer.

The erratic temp indicates there is air in the system and it needs to be bled out thoroughly. Using a vacuum fill method is the best way to get all the air out.
