sounds like an IAC motor. that stands for idle air control motor. it adjusts throttle to keep at steady speed. could possibly be throttle positioning sensor though. pay attention to see if it does it worse while mashing breaks because if EGR is stopped up it can cause symptoms similar too.

Its on passenger side under rear seat cushion. Get in back seat FACING rear seatback, grab under lip of bottom seat cushion, and pull straight up. Disconnect seat heater connector (if so equipped) on passenger side and remove seat bottom. Tada! There ya go! Oh... btw. Its a $150 battery due to the venting system designed into it to vent fumes through a tube to the outside world. Thanks Cadillac!!! :(

check all your fuses first. if they are all good replace the blower motor resistor. this controls alll the speeds for the blower motor and also suplies the power to it

SOURCE: my 1998 caddilac deville low oil pressure light on...

the low oil pressure light can be a faulty oil pressure sensor.But mostly its the pump itself. open the oil pan and check if the net is chocked if not then replace the oil pump and do install the new o ring supplied with the pump. And try changing the oil on time and a good brand is important. (if the problem still exists then u need to replace the crank barring and the cam bushings..Just kidding).

3. Remove the 2 bolts securing the thermostat housing to the intake manifold.
   
4. Remove the thermostat housing.
   
5. Remove the thermostat and O-ring from the housing.

1. Install the thermostat and new O-ring to the housing.
   
2. Install the thermostat housing to the intake manifold. Tighten the thermostat housing bolts to 18 ft. lbs. (25 Nm).
   
3. Refill the cooling system using a 50/50 mixture of water and ethylene glycol antifreeze.
   
4. Install the air cleaner and beauty panel, if removed.
   
5. Start the engine and check for coolant leaks. Allow the engine to come to normal operating temperature. Recheck for coolant leaks.
