    Mine got hard to start and would sputter for a half minute or so. Sometimes the CEL would come on but then clear itself once things righted themselves. Sorry, I don't know what code it was throwing.

    Mine stumbled a bit on acceleration..right out of the gate. Dealer replaced immediately and 30k miles later (car has 32K on it) still no problems.

    My '08 Cooper S is going to the dealership in the morning. Over the last week I've had the sputtering on cold startup five times. The last 2 times I've gotten a yellow CEL. Code is p3091- fuel pressure at fuel rail under the minimum. I'm betting that it's the hpfp. Mileage is 32k.

    Is it possible that an erratic idle could be a symptom that it's starting to become a problem? No CEL on, no vacuum leaks, etc.
