Please help: 01 m3 misfire.
After 2 days if driving though snow in ny my car suddenly sounds like its got misfire upon start-up. (Keep in mind it was running fine 2 hours ago). So i check out the codes and p1348,p1350 and p1351 show up!!!. I read that its a cylinder 4 and 5 that have misfire. Now can that happen to both cylinders at once? And does anyone have experience with this. Im hopeless and counting on this forum like i always successfully do. So i need advice, could it have been the cold? Driving though snow? A recent oil change i did wrong(doubtful)?
