    Default acceleration and hesitation on my 535i

    Performed the stomp test, got the no fault code. The e34 hesitates or misses on acceleration. Where should I start? Cleaned the intake and installed new air filter. Anyway of checking the ignition wires?

    Use a multimeter and test
    distributor cap
    distributor rotor
    all ignition cables and their plugs

    easy to do. Details are in the Bentley manual. If you do not have a Bentley, just test them all and the one which is different is faulty.
    I recently had a friends E32 750 for checking here, engine was runniung really rough. Found the distributor had haircracks, 8 out of 12 ignition wires did not have the right Ohm.
