Nateh 0 Report post Posted August 23, 2006 Hey, I have a 1991 E36 318i and when i start it from cold it seems to rev hunt (tacho moves up and down by a few rpm on its own). I have also noticed it doing it randomly when sitting at lights usually on a downward slope and does it really hardout when steering wheel on full lock, iMy tyres are 205/80/R15 off a 1996 model E36 so this shouldnt be much too big, can anyone help me out on this or is it normal?

MADBMA 0 Report post Posted August 24, 2006 few tips to try before paying the big bucks: your wheels have nothing to do with it! 1). check the vacum hose after the airflow meter, check for any cracks holes and what not, engine could be sucking in more air then what the airflow meter is providing the computer. i solved with problem with a bit of cloth tape. 2). Clean the idle control valve with some carbie cleaner. 3). spark plugs, change Quote Share this post Link to post Share on other sites
