[QUOTE="STAMPEDE3, post: 2053771, member: 9007"] The rears have nothing to do with the A/F ratio, only the fronts. The rear O2s only tell the computer if your cats are working properly which is why the CEL comes on with the cats removed. Mils don't always work, they only amplify the rear O2 signal to adjust the reading so the computer thinks the cats are still there. If a rear O2 sensor is bad and reading out of range the Mil can only compensate so much and the reading will still be out of range and the CEL will still be on. Best bet is a chip to turn the rear off. [/QUOTE]
