Message	is sending too much fuel. MAF, temperature, O2 are the values the computer uses to adjust the duty cycle of the injectors. If, as you say, it was fine at first and then it became rich, there is a sensor input sending the wrong info to the computer. If you cannot find it, how about using a chip with a different tune? Or.., retune. Bernie might be right after all.
