    Engine Light
    Is it true that when your engine light comes on, it has nothing to do with how the car/engine is performing?

    Well, yes and no... It can mean there is an issue. Sometime it can be a major problem, in which case you will notice the cars performance (or it dies or won't start). But it can also mean that its time to change the oil :)

    What kind of car is it? (year, make, model)

    The Check Engine Light (CEL) comes on when there's a problem affecting emissions. Most of the time, it indicates a problem with the engine and/or transmission. Anytime the CEL comes on, get the codes stored in the ECU's memory read right away. Many auto parts stores will do this for free.
