Hey Ras,

Before we go jumping of the bridge, let's get your car scanned so we can see what is causing that light...? Might be something simple. Cottman's will do this scan for free. Resubmit to me the code numbers, not their definitions I need the numbers, then we'll take the next step to an easy fix...!
