This morning when I started my car it took munch longer then normal to start the engine. Got the 'Check Engine' light on and got the warning saying :

"Engine Malfunction : Engine with half the power"

So I turned off the engine and restarted the car, started normal with no warning but the 'Check Engine' light is still on.

Has anyone else experienced this problem or have any idea as to what is going on here.
