It's a 1998 Grand Marquis. The engine was just checked out and everything's fine. Any ideas why this might be happening?

It could be something faulty with the wiring, but often times the Engine Light is the 02 Sensor. You can take it to most autopart stores to have a diagnostic test run for a lot cheaper than a mechanics because they would rather have you buy the parts there. Some places even offer the service free.

The "check engine" light on a car isn't there only when your engine dies on you. It flashes when the sensors in your engine detect a low level of any fluids or the potential to overheat. Even if there's nothing wrong with it, it's a good idea to get preventive maintenance done and keep a problem from creeping in.
A similar principle is employed by the "low fuel" light on a car; the sensor in the gas tank's detected only a minimal amount of fuel, it's not empty yet.

The Check engine light can come on for a variety of reasons, some very minor, like not having your gas cap on tightly, or having an airleak in the gas cap. It is also programmed to come on a certain number of miles so you will take it to a dealer to have a good inspection. Most mechanics can reset it for small fee.

It depends on the number of miles that are on the vehicle. Lots of times cars have a set number of miles that throw a code on to your car's computer that make your check engine light come on. It is a way that manufactures can make sure that you bring your car in for servicing and to also make sure that you get your car checked out to stop any problems before they are problems. If you just had your car checked out, call the mechanic and ask him to hook your car up to his scanner. He can check the code to make sure that there is no problem and then rest the computer. However, lots of times, when cars get over a hundred thousand miles on them, they have more issues that need resolved. If you have a muffler problem, like a catylitic converter, that will make your check engine light come on also. Take it back to your mechanic just to be safe.

Sometimes the wires controling that light can get messed up so it turns on when you are fine. That happened in my boyfriends old thunderbird -- the light was on all the time but the engine was fine.

I've had the same thing happen to me. Check that your gas cap is on correctly. I was told to take it off and put it back on. After I drove a few miles the light went off.

sometimes the sensors go wonky. Usually when they change the gas blend in summer and winter.
And sometimes I think the engine is just lonely and wants to know you care.
