Aren't there codes that get stored on occasion that do not throw a CEL ??
Yes...but there very unlikly, but it is possible. The only one I know of is if your fuel level sensor is bad. See the way I undersatnd is that all the codes that pose a problem with the driveability of the car will throw CEl's, including some transmission problems.
But when it comes to air/fuel and gas mileage, it may not throw a CEl, like with fowled spark plugs, but i believe bad wires might throw a CEL.
BUt if it's a precat it would mostlikly throw a CEL.
