If your engine is ideling fast its probably temperature senser. There is no adjustment for idle. that last answer is not entirely true. u can adjust the idle. but it depends on if its a throttle body unit that looks like a carburetor or a smaller unit. on a TBI unit, there is a screw u can adjust but the only way to adjust it is with the right tool. its not a Philips screw or straight blade. but if its idling high or fast it might be the idle air control valve. the one went out on my 1985 sunbird and caused it to idle funny.

On a 1989 Cadillac Seville, the water pump is typically located at the front of the engine, mounted on the engine block. It is driven by the serpentine belt and usually positioned near the lower section of the engine, close to the radiator. To access it, you may need to remove any components obstructing the area, such as the fan or belt. Always refer to the vehicle's service manual for specific instructions and diagrams.
Head gasket? Low coolant level? Water pump not circulating coolant? Thermostat not opening? Radiator plugged or restricted?

If the idle is constantly high, I would adjust the idle control on the left hand side (facing the car) of the throttle control body.

My 89 shadow did that. The 89 and the 94 have similar body styles so id have to say that it's your oil sending unit(a little wire with a red casing) became detached. Itll make your car Idle low and your car will stall and stutter
