Your E39s all being reliable and behave eh?Well mine is sick today out of no reason. This morning it was all fine when I took her to my office. After finishing my work and left about 8 hrs later, the car started but with some vibrations. I thought maybe it was the engine not warm enough but never happened in the morning before though.Seems like the car now fires on 5 or less cylinders. The symptom is similar to a car misfiring or running with 1 cyclinder less. Feels very sluggish and hesitates. Not the usual smooth operator of the 6pot.Any of you experienced this before? What could be the cause?Thanks for any kind advice.Cheers.</p></blockquote><p></p>
