    Hi Matt

    The is is a cracking car! Give the old gal a service first,then report back on the miss fire!

    Did the fuel gauge work then stop? Or never work?

    Welcome to BMWOC :)

    Misfire could be plugs or a dodgy coil pack,the heater is more than likely the 'hedgehog' resistor,and fuel gauge is probably a fuse blown ????

    Snypa and Ian covered it mate

    Get the is in for a service and see if it changes anything

    A blown fuse wouldn't cause it.

    Where is the misfire? Is it noticeable on idle or higher revs?

    As it is a four-potter it would be hard to eliminate a coil-pack by just pulling off but bang a high-voltage meter across "Earth" and its "Low tension" feed and notice any shortfall...

    ... Other items to inspect are:

    MAF

    TPS

    CPS

    ... And any air-leaks via intake hoses.

    Good luck ;)
