After it reaches about 200, does the coolant in the radiator start to flow? Does the upper hose get hot when this happens? This is an indication that the stat is opening correctly. Does the water pump spin freely by hand when the belt is off?

There'* alot of stuff to check. But it'* pretty easy to narrow down if you do it methodically. The 92'* will tend to run hotter (except the SSEi or SC SSE) because you don't have an EGR valve. Switching to a 180 is a good idea, but I'd try to narrow it down first.

I'm betting if you flushed out the spaces in the radiator (from the outside), have the cooling system flushed, and switch to a 180, you'd see an overall improvement.
What he said!

It could be something real simple like some air bubble got trapped in your system when the coolant ran low and that could cause that yo-yo effect on your temp. I would replace the thermostat and, if it'* been awhile, flush out the old coolant and put in the new.

It'* almost never one cause. It'* a combination. Go after the whole ball of wax, and you'll get it.
