I have a 98' Cadillac deville and it should constantly read around 197-201 when you are driving. It will definitely increase when you come to rest: example at a street light. something is definitely wrong and should be checked.

Gas on 2000 Cadillac deville?

Idk what exactly u want to know. But i have a 2000 cadillac deville and i put mid-grade in the tank but regular does work fine with no problems. The mpg varies from anywhere between a high 17 mpg to close to 20 mpg because the dash is digital and it changes often depending on your driving. Its not too bad for local driving and the cruise control on mine never worked so im sure by using that you save more gas also. Hope this helped

Why would the temperature on a 1993 Plymouth Voyager 30 go up when parking and not when driving?

Because when your moving, air is moving at the radiator, cooling it down, thus cooling your coolant down, thus cooling your motor temperature down causing the coolant temperature sensor to pick up a lower reading and relaying it to the gauge. Depending on how high it is in "Park" you may have poor circulation, a broken or missing fan shroud, weak water pump impellers, low coolant, inactive coolant fans or a bad fan clutch.
