There are many reasons why that "check engine" light might come on.
The ECU has logged a fault that you can dump the codes to decipher
what the cause was.  Next time this happens, when you reach your
destination, don't shut off the engine, and dump the codes.  Full info
on how to do that can be found at http://www.sjmautotechnik.com
