Do you have a Check Engine light on? These annoying little lights that flash gloom and doom in your vehicles dashboard, however, it should be known that their sole purpose is to give a warning, not to try and ruin your day.
Check Engine lights can come on for MANY different reasons. Anything from a loose gas cap to spark plugs that need to be changed, to a worn out O2 sensor can be the culprit. It is always best to have the light diagnosed by an experience professional to determine the true cause of the light coming on in the first place. The Check Engine lights entire existence is meant to inform the unsuspecting vehicle owner that there is some sort of a problem within the workings of the vehicle.
Even if your vehicle seems to be running perfectly fine, you should still have the light checked out. The light does not come on unless there is a problem, and most cases, you can fix the problem for less money than if you were to put it off and allow the problem to get worse. Example: If you have an engine misfire due to needing new spark plugs and fail to replace them, then you run the risk of over-stressing the rest of the ignition system components which can shorten their life expectancy and lead to premature failure. In turn, it takes the price of a tune up and turns it into the price of having to replace some or all of the entire ignition system. Either way you’re doing a tune up, but it exponentially lowers the risk of having to replace more parts and pay for more labor than are necessary.
The same can be said of all maintenance that your vehicle manufacturer recommends. It is important to note, that while you can go to most automotive parts houses and have them give the “free code reading”, this is not a substitute for an experienced mechanic diagnosing and repairing the problem correctly the first time. Remember, the automotive parts houses are in business to sell you auto parts and mechanics/technicians are in business to repair your vehicle correctly the first time.
