Question:         Today’s question is for those of you with smaller cars.  True or false: The effects of a bad spark plug are twice as noticeable in a 4-cylinder car then they are in an 8-cylinder car. 

Answer:           True.  At 55mph, each spark plug in a typical 8-cylinder engine fires 750 times per mile.  At the same speed, each spark plug in a 4-cylinder engine must fire 1400 times.  If only one plug misfires in the 4-cylinder engine, that car will suffer more than twice as much as an 8-cylinder car with the same problem.

  *Enjoy the pleasures, convenience, and economy of your smaller car, but make sure you’re especially conscientious about keeping the engine tuned.
