    Ford ute flat low revs

    Ford Ford Advice Ford Falcon Ford Falcon Advice Ford Falcon 2002
    My six-cylinder dual-fuel AU Ford ute runs unevenly at low revs and feels 'flat' or misfires at initial throttle opening on both LPG and petrol. It is particularly noticeable around town in second or third gear at around 1500 rpm. The throttle body and injectors have been cleaned, and the fuel pump, fuel pressure regulator, spark plugs, plug leads, ignition coil, throttle position sensor, oxygen sensor, knock sensor and idle air control valve have all been replaced. Resistance measurements of crank angle sensor and camshaft sensor are within specifications. Any suggestions?

    I would be looking for a vacuum leak. Check all hoses on the engine looking for splits, also check for a split brake booster check valve.
