Have you done anything to your car lately which could have brought this on? I would make sure the connection on the sender is clean otherwise just replace it, they don't cost very much anyway. If it still persists then perhaps your dash is having grounding problems.

thanks jeff. well the only thing that
may have brought it on is sitting outside in sub zero temperatures,, hehe,. but i don't think so. it ran after that and warmed up with 'normal' temperature guage operation (it usually sits pinned on top of the top loop of the '8' in 80. ) the sender tip is clean.
no other issues i can think of like low or no heat or (god forbid) steam running out of the engine in an overheat situation
i was thinking t-stat or aux pump but am quite sure there would not be any heat at all if that were the case, right?
the other guages work in the dash ok so i'm down to the sender,
the one on the block right next to the IP. are there any other sensors that are hooked up to the guage?
