Welcome, Friend ! Codes should tell the tale on the light. As for maintenance, simple things like ; a coolant flush, belt & hoses (rad & htr), clean MAF & throttle body, air filter, new plugs & wires will go a long way for short money in delivering smooth running longevity. Check brakes & struts along with front end parts and replace as needed for better drivability. Shop around for your parts (ebay, RockAuto) or locally and take advantage of rewards programs (Adv. Auto) to score more savings on top of doing the work yourself. Good Luck !
