Zank,
Is it a big sweeping change in the temp guage needle???
Either you have a really big air bubble in the coolant system (you need to get the air out), or your temperature gauge sending unit is crapping out. The sending unit is located on the engine block behind the distributor. Kind of hard to see & access, unless you take the distributor cap off.
HTH.
