CEL for 25 minutes?!?!

[napkinthief]

I just installed a new radiator yesterday, and its fine, and today I wired up an amp, but the fuse is not in.

I turn my car on and go out and close the trunk and the CEL is on... I turn it off and back on and it stays on, but I had work so I left, then at work I turn the car on again and the light won't come on....what happened?

You mean the CEL doesn't come on even for a second when you start your car? It should at least come on for a second, if not the bulb is probably toast.

Anyway, if the CEL does come on and stay on, drive over to autozone and they'll retrieve the code for free.
