Thanks for the help but I think the car is running RICH, not lean during warmup. I know this because there is a BIG black streak under my tailpipe on the garage floor and black smoke greets the folks on the freeway when I pull out in front of them (come on, when you drive a big SEL, they expect that kind of thing).
