Do not trust any immature automobile engineer for solving the car engine. The engine should be checked to know the case of the car engine problem and know the car engine code. The engine P1193 Code is found when the car engine is tested. The engine problem is small but serious, a spark plug makes the car move. Its purpose is to explode the crushed fuel in the engine. A worn spark plug will cause a weak spark. It may even stop ignition totally, or cause ignition at the mistaken time. A fail will move engine power and fuel economy and reason enormous sums of possible harm.
