Best Answer

When the check engine light or MIL (Malfunction Indicator Lamp) is blinking approximately once every second it is indicating what is called a Type A Misfire. A misfire occurs when one or more cylinders is not contributing to the power output of the engine. Type A misfires are damaging to the catalytic converter on the vehicle and are therefore deemed very harmful. Misfires can be caused by a variety of things but can generally be classified into one of three categories: Fuel, Ignition, Base Engine. Fuel could be a malfunctioning injector for example. An ignition example could be a spark plug that is not firing due to a bad ignition coil. A base engine example could be a bent connecting rod or a hole in a piston. Catalytic converters can be quite expensive to replace so might want to get it repaired sooner rather than later.
