Re: check engine soon stays steady, blinks periodically, rough idle, driveable?

yeah, blinking MIL is there to protect your catelitic converter...as mentioned it indicates a misfire that can burn out the converter. When the light turns on, that means one thing and one thing only....the computer has stored a code relating to the problem (wich can be one of hundereds of things)...I got fed up with friends and family ignoring these lights so I baught a code scanner. Best 100 bucks I ever spent. Chances are you have a heavy misfire from a bad plug wire or something. You will likely get a misfire code...At wich point you should replace your plugs & wires.
