It is a remarkable testament to humanity's narcissism that we know the number of books in the US Library of Congress on 1 February 2011 was 22,194,656, but cannot tell you -- to within an order-of-magnitude -- how many distinct species of plants and animals we share our world with, Lord May writes.
Engine misfires can be caused by a list of faults, but there are a few suspects that occur more than others. The primary villains are simple â spark or fuel â usually manifesting in spark plugs, plug wires, the coil(s) or the fuel-delivery system.
In ICE engines with four strokes, the complete engine cycle takes four strokes: there is intake, compression, ignition and exhaust. Misfire means that ignition was attempted with the spark plug but the cylinder did not fire. It missed. When multiple misfires occur, the engine runs roughly and loses power quickly. Usually something is wrong because a reasonably tuned properly running engine will not miss even once in millions of cycles.
