Smoking E46 - not in the good way either
So I just started up my car and she is just spewing white smoke out the tailpipe constantly. You rev it and its just worse. Last year I had to replace the CCV and valve cover gasket. Not sure what this issue is now. She also runs a little rough - revs moves around at idle from 800 to 500 and back and forth.
I'm guessing perhaps an O2 sensor ... anyone have any input. She's on the flatbed right now headed to the shop. Man I hate the winter.
She's an 05 325i with 116,000km. All maintenance and inspections done.
