The computer does try to re-mix depending on what the sensors all say. The O2 sensors feed info from the intake and exhaust with how much oxygen is coming in and how much is going out after combustion. The computer adjusts all of this to help the engine burn cleaner and safer. It adjusts the mixture up to something like 10 times/second so it's constant adjustment.

Like Brucelee says, there are certain parameters set in the computer that determine how to change the mixture. If it can't get back to the parameters you will get a CEL and could damage the engine. The only way to make the computer accept the new parameters is to re-program it (good luck) or put a chip in that will do the re-programming for you. I'd think twice about it, though. The computer was designed to protect the engine and make it perfom at its' best. If you change the parameters and the computer does not realize the engine is being harmed, you lose all of your protection.
