    Hello all
    I recently purchased the vehicle in the US and transferred it to Israel - BMW E23 735i 1985
    since i got it i am facing problems...
    I could not start the car - Ireplaced relay and the engine started
    The engine misfire badly, a rich mix and random blemishes:
    I replaced the following///
    spark plug
    idle speed sensor
    mass air flow meter
    oil, filters
    still no results...
    thanks in advance for any help

    And coolant temp senaor, these cars are very sensitive to that particular sensor.
