Hi all. Problem with my 318i n42. Surprise surprise. The car has been hesitating from 1k up to 2k revs when cold and lack of power in that rev range. I unplugged the maf and it seems a lot smoother and driveable. I take it a new maf is required. I cleaned it a couple of weeks ago when I changed the air filter. And when it comes to fitting a new maf is it just plug and play. Cheers for looking.
