Parts of the disa valve are made from inferior quality plastics. Over time, the bell crank lever wears out, leaving the unit in a state of disrepair. The disa unit will rattle when the engine is running on idle. This can be confirmed by unplugging the disa valve to check if the rattle goes away. A faulty disa valve will cause poor engine performance.
