Default CEL upon startup

A few weeks ago my car got the CEL, i didnt think much of it and reset it. Well today when leaving for lunch it came on again. I have not had one for a while (cant remember ever having one) and am wondering about ideas. When I went back after turning the car off it was not on and car fired right up. My mods are in my sig if you have any questions and have all been installed for a while. I know its kind of vague but just want some ideas of what it may be. Thanks

Go to an Autozone and get a readout of the code from their OBDII scanner. Don't blindly reset CEL's as they are trying to warn you of a condition that's potentially damaging to the engine. At least find out what it is before ignoring it

nope, it erases the memory on the PCM. only hard codes are stored (airbags)
