 Unfortunately, it seems that a Check Engine light problem usually ends up with professional auto repair time. But don't mortgage the house just yet. There are some fairly common issues that can make the "Check Engine" light come on. The good news is that these issues can be corrected without a lot of time or money

    * Loose gas cap -- Some cars measure how much pressure is building up inside the gas tank by tracking your driving style together with how much pressure is in the tank, then setting off an alarm if it varies a certain 

percentage from the average. The sensor thinks something is wrong and triggers the Check Engine light. You can try to tighten the gas cap and then wait about a week. If the light hasn't gone out by then, call your auto repair specialist for help.

    * Wet Engine -- An electrical disturbance under the hood can cause a sensor to take a funny reading, triggering the Check Engine light. Even water dripping onto a spark plug wire can set it off. However, the most common occurrence is the vehicle owner who sprays his engine down at the high pressure car wash, shooting water into every crevice, triggering the light.

    * Bad spark plug wires -- As spark plug wires age and wear out, they may develop tiny cracks which can let little bursts of electricity out. This electricity was supposed to be going to a spark plug, and since it didn't, the engine will misfire slightly, meaning one of the spark plugs didn't spark enough, causing the Check Engine light to come on. If your spark plug wires are looking frayed and worn, schedule an auto repair service to check them out and have them replaced if necessary.
