I'm throwing out scenarios. I've had injectors throw me for a loop and cause all kinds of crazyness. If you believe everything is easy and the same every time then I got some news for you. I've also seen cars running very bad and with crazy lean/rich mixtures throwing no faults. I've been on the BMW brand for 10+years now. The only thing I know is, just when you think you have seen everything you find something new.
