A faulty ignition module can cause a vehicle to overheat. The vehicle may run and then lose power suddenly due to a rise in the engine's temperature. Once the engine cools, the vehicle will start and run until it overheats again.
In two days the Dow Jones industrial average fell by 25% (ending on Black Tuesday, 29 October). The volume of stocks traded set a record that was not broken for 40 years. When it finally reached its record low in July 1932, the Dow Jones had fallen 89%, and it did not recover to 1929 levels until 1954.
In terms of the stock market, nearly three years after the 1929 crash, the DJIA dropped 8.4% on August 12, 1932. Where we have experienced great volatility with large intraday swings in the past two months, in 2011, we have not experienced any record-shattering daily percentage drops to the tune of the 1930s.
