Question about 2004 Pontiac Grand Prix
This is one of two things, first theres a problem with the engine , the way it runs its loosing power or if the wheels spin and the computer picks it up then it will reduce the power to avoid wheels from slippping, this is like when driving in the snow, now if the check engine light is coming on with this message then you have a problem and the first thing to do would be to have the codes pulled and see what codes are stored. what happens is the computer sees a problem and turns on the light and stores a code for that problem. for example there may be a code that reads po300 multiple misfires. this code would mean the computer has seen the motor misfiring and with some testing the problem can be found. there are many auot part stores that will scxan the computer for free and give you a read out with the code. if you get the codes i can help you further, have a good day.

Tips for a great answer:
The MIL turns OFF after the engine is started if a diagnostic fault is not present.
The MIL remains illuminated after the engine is started if the control module detects a fault. A diagnostic trouble code (DTC) is stored any time the control module illuminates the MIL due to an emissions related fault. The MIL turns OFF after three consecutive ignition cycles in which a Test Passed has been reported for the diagnostic test that originally caused the MIL to illuminate.
The MIL flashes if the control module detects a misfire condition which could damage the catalytic converter.
When the MIL is illuminated and the engine stalls, the MIL will remain illuminated as long as the ignition is ON.
When the MIL is not illuminated and the engine stalls, the MIL will not illuminate until the ignition is cycled OFF and then ON.
