Question about 1990 Cadillac SeVille
The problem you describe could be result of a few different things: 1) Check your Idle Air Control (IAC) sensor/motor. This sensor is located on your vehicles, throttle body. The purpose of this sensor is to control the car's idle under various operating conditions including ambirnt temperature. In order for it to function correctly, the internal components must be clean (meaning, little or no carbon build up) and it must be undamaged. Sometimes the IAC can be cleaned; however, if this cleaning procedure is not properly done, the IAC can become damaged. This sensor is also sometimes called the "Cold Start" sensor. A new IAC will cost $50-$100. 2) Check you Coolant Temperature sensor. This sensor is located on the top of your engine and is screwed into your intake manifold. When this fails your car will experience starting problems when cold outside. A new Coolant Temp sensor will cost about $100. Take a look at these two solutions first. My guess is your IAC needs to be cleaned or replaced. Good Luck!
Please remember to rate this solution. Thanks!
