so I dont have mil eliminators on my o/r h pipe and I've lived with having the cel on for the last 1 1/2 years. about 2 months ago the light randomly turned off, and hasn't been on since. i've also put over 1000 miles on my car since then. The light isn't burned out because it lights up when i put the key in and tune it, but its off when the engine is running. did my cel just give up trying to tell me my car had a problem? I really dont mind not having a bright yellow light starring at my face when I'm driving, but I want to make sure the reason its not turning on isn't anything more serious
