Mitsubishi Repair: Expo 1992, coolant temperature sensor, engine coolant temperature sensor

Question

Answer
Billy,
Your problem may be a faulty engine coolant temperature sensor or a faulty Idle Air Control (IAC) motor.  If either of these items are not working properly, they can cause your engine to stall out once the engine warms up.  Your problem can also occur if your car's computer is malfunctioning.  Have your mechanic inspect those items to see if they are functioning properly.
Good luck!
