08 Clubman sputter/won't start
My Mini sat for 12 hours, started fine but sputtered on acceleration until high revs, then it ran fine. Would run fine at highway speeds until I tried to accelerate and then would sputter until high revs again. At idle it was very rough, idle at about 500-800 RPM. I noticed my fuel mileage was around 50 mpg for my trip home, about 50 miles. It sat overnight, about 10 hours, and would turn over but not start. I changed spark plugs, but same thing. The check engine light in speedometer was yellow and would flash when accelerating. I plugged in my ODB reader and got fault codes p1497, p0507, p0300, p0302, the same 4 pending, and p15e8 pending. I can't find anything in my research that has any of those codes and a "won't start" problem. I want to check the coil packs with an multi-meter, but am not sure how to go about it. Anybody have any ideas?
