Hi Guys, I have a V36 sedan and had a problem especially in the mornings when I first start the car. When taking off it stutters at low rpm. I used injector cleaner & filled up at a new petrol station. That seemed to work for a while, then same thing started again. I removed my air filters
& they were filthy. I replaced both with K&N filters, ever since the car runs like a dream. Never had a problem since its been 6 months now. It sounds too easy but I'll be starting off with the easy stuff first...Good luck..
