    Land Cruiser LPG explosion

    Toyota Toyota Advice Toyota Prado Toyota Prado Advice Toyota Landcruiser Prado 1998
    Recently, when I attempted to start my 1998 Toyota Landcruiser Prado on LPG there was a large explosion and the air box was blown apart. I have since learnt that this is not uncommon for vehicles fitted with LPG systems, and that the condition of the spark plugs and leads are critical. But these were replaced only 12,000 km and 20,000 km ago. Having replaced the air box what can I do to prevent this happening again?

    The explosion is a result of the air/LPG mixture in the intake manifold igniting, most likely set off by a stray spark. Change the plugs and plug leads again, they are usually the cause of this problem.
