Look you should always take a service engine light seriuosly. its telling you something in your engine needs service. you can take it to any local autozone ect and they will scan it for free with a diagnostic tool and tell you what you need to do to fix it. it sprobably something a simple as a tune up you know oil change plugs and wires that is usually what causes that light to come on

The Service Engine Soon light is a notice from the vehicles on-board computer that a problem has been detected somewhere, and service is required. You can isolate the problem by having the "trouble code" displayed for you at an auto parts store for FREE to determine the exact problem, and possible causes. This should be done FIRST, so that you strategically approach the problem directly instead of spending unnecessary money "guessing or assuming". If you are trying to save a few bucks, you may want to invest in a Chilton's manual for you vehicle as well for step-by-step repair, and diagnostic info specifically for your vehicle. I hope this helps,...and good luck!!
