    I've been getting this code pair within say 15 miles after I clear the codes, they always come in a pair. I've turned the battery off for half hour and cracked it back up letting it sit for 10minutes too. I've searched extensively on the net and there's not a lot of data on them, I'm not even sure what they mean but I'm guessing "too rich banks 1 and 2" but I could be wrong. If so, vacuum leak? MAF? Injectors? Does the fact that my bypass valve is wired open matter? HELP!

    I think you need to wait for Dave Helms to come along. He has a list of all ferrari specific CEL codes, which these two are.
