    Hi, so i have an issue with my e36, the engine is m40b18 and it missfires bad. So i changed:
    Fuel pump
    Spark plugs
    Spark leads
    Ignition coil
    Crank sensor
    Maf
    O2 snesor
    And nothing helped, starts good, ibdont think that the timing belt hoped

    Change to another gas station and put better gas, use a couple bottles of fuel injector cleaner over the next couple of tanks.

    One or more injectors may be leaking.
