I've had the Check Engine Light come on a few times since I bought the car. After turning off the car though it goes out. When I check the ECU it still has the codes stored in it. The CEL is not on though. I've even pulled the 7.5 backup fuse under the hood to clear the ECU like good ol Haynes says to but the codes are still there.

If the problem is still there why doesnt the CEL come back on?
