how many miles on the car, Allot of times the service light will come on because the Cats are starting to clog up and will not throw a code but the will turn on the service light or the car is running on the hot side, this will also turn on the service light !

184,000. It's just really been a great car so trying to keep it bit longer. I forgot to add when the light first comes on it runs little sluggish but once I start driving its fine

Also, all gauges on the car are good, no issues. Run the system check for fluids, engine, etc all ok
