New plugs and it runs worse  |
I replaced my air filter back in December and I get the same thing. I have a 328i and it stumbles for the first 10 seconds or so when starting up then runs smooth. On warm days I haven't noticed it. My gas mileage has been shot to hell too. I was averaging 26-27 MPG before that and not I'm getting anywhere from 21-23. I've had it less than a year though, so I guess it could just be the cold weather... I'm going to look into it more when it gets warmer if it doesn't get better.
