Rough Start

[Andries]

I have a 2005 X3 and when I went to start my X3 it barley turned over and it was running rough and the whole care was shaking. It finally cleared itself and seems to be OK. Has anyone else experienced this and what could it be?

Thanks

I had it after a bad tank of gas. Happened for a couple days in a row, then when filled with gas from a different station, cleared right up.

Same thing happened to me. I was using the lower octane rating gas at the time. No problems since.
