When the check engine light in a 1998 mercury mystique comes on what does that mean?

It means you need to go to Autozone or Shucks/Kraagen and have them read the codes with the diagnostic code reader which they will usually do free of charge. Something in or on the engine is malfunctioning and needs repair/replacement. The diagnostic code will tell you where to look for the problem. Oxygen sensor is an example of typical problem discovered but all engine sensors are monitored.

What causes a 1998 mercury mystique check engine light comes on then the oil light and all of sudden the car shuts off?
I am having a problem right now with my check engine light too. I don't know why your motor shuts down, but in the book it states that when your check engine light comes on, you are having a problem with your emission control. For you, it might be a sensor is shutting down your engine. I know last month Mister Transmission was having a free check out your engine special, so you might want to call there to see if they can put your car on a diagnotic. Good luck

Need to get it scanned to find out the code. You got a problem that comes and goes. The problem comes then sends a code then after so many starts if it is not there the light will go off. Go to a place like Advance Auto and they will scan it for free and then post the code.
