There is a failure/malfunction some where in the vehicle to kick on the engine light, so I suggest repairing this failure. If the engine light is triggered there really is no known way to tell if something else has failed due to the light being on for your previous concern, and going un-repaired can cause you not to know if you may have other concerns. You can go to your local auto parts store and have them read the codes from your turning the check engine light on.
First, if you live in a state where you have to do emissions inspection, your vehicle will fail if the check engine light is on.
Second, this light comes on when there is an issue with one of the sensors on the vehicle. Leaving this unchecked could cause more serious problems. I would recommend finding out what the code is and then you can make a decision as to where to go from there.
